Level 3 Sports Massage Therapy A/P Mock Paper By Tom Gallivan

The correct answer is Sliding Filament Theory. This theory explains how muscles contract by proposing that actin and myosin filaments slide past each other, causing the muscle to shorten. This process occurs when myosin heads bind to actin filaments and pull them towards the center of the sarcomere, resulting in muscle contraction. The Sliding Filament Theory is widely accepted and supported by experimental evidence.

The ischium is not part of the axial skeleton. The axial skeleton consists of the skull (including the cranium), vertebrae, and sternum. The ischium is actually part of the appendicular skeleton, which includes the bones of the limbs and their attachments to the axial skeleton.

The two major divisions of the skeleton are the axial skeleton and the appendicular skeleton. The axial skeleton includes the skull, vertebral column, and rib cage, which provide support and protection for the vital organs. The appendicular skeleton consists of the limbs, shoulder girdle, and pelvic girdle, which are responsible for movement and locomotion.

Cancellous bone is not a classification of bone because it refers to a type of bone tissue rather than a specific classification. Cancellous bone, also known as spongy or trabecular bone, is found inside the outer layer of compact bone and is characterized by its porous and honeycomb-like structure. It is responsible for providing structural support and strength to bones, but it is not a distinct classification like irregular, flat, or sesamoid bones.

Thyroxine is the hormone produced by the thyroid gland that helps regulate the metabolism of all cells and tissues in the body. It plays a crucial role in controlling the rate at which the body uses energy, thus affecting various bodily functions such as heart rate, digestion, and body temperature. Thyroxine is essential for maintaining normal growth, development, and metabolism in humans.

The sinoatrial node is used as a pacemaker in the body. It is a small cluster of cells located in the right atrium of the heart. The sinoatrial node is responsible for generating electrical signals that regulate the heart's rhythm and initiate each heartbeat. These signals cause the atria to contract and pump blood into the ventricles. Therefore, the correct answer is Sinoatrial.

The correct answer is Pharynx, Larynx, Trachea, Bronchi, Bronchioles, Alveoli. Air enters the respiratory tract through the pharynx, then passes through the larynx, trachea, bronchi, and bronchioles. Finally, it reaches the alveoli, which are small air sacs in the lungs where gas exchange occurs. This sequence of structures represents the correct passage of air through the respiratory tract.

The function of compact bone tissue is to provide strength and support to the skeleton. Compact bone tissue is dense and hard, making it ideal for providing structural support and protection to the body. It forms the outer layer of bones and helps to withstand the forces and stresses exerted on the skeleton during movement and weight-bearing activities. Additionally, compact bone tissue also contains channels and canals that allow for the passage of blood vessels and bone marrow, further contributing to the overall function of supporting and maintaining the health of the skeleton.

Sight is part of the sensory nervous system because it involves the perception and interpretation of visual stimuli through the eyes. The sensory nervous system is responsible for receiving and processing sensory information from the external environment. Sight, along with other senses such as hearing, taste, touch, and smell, allows us to gather information about our surroundings and make sense of the world around us.

The pancreas is needed to lower blood sugar levels. It produces insulin, a hormone that helps regulate blood sugar levels by allowing glucose to enter cells, where it can be used for energy or stored for later use. Insulin also helps to inhibit the production of glucose by the liver, thereby reducing blood sugar levels.

The cell body is the main part of a cell that contains the nucleus and other specialized organelles. These organelles perform various functions necessary for the cell's survival and functioning. The nucleus houses the cell's genetic material and controls its activities. Other organelles such as mitochondria produce energy, endoplasmic reticulum synthesizes proteins, Golgi apparatus modifies and packages molecules, and lysosomes break down waste materials. Therefore, the cell body consists of the nucleus and all associated specialized organelles.

Smoking is the correct answer because it is a well-known risk factor for arterial stiffness and loss of elasticity. Smoking causes damage to the inner lining of the arteries, leading to the buildup of plaque and inflammation, which in turn reduces the flexibility and elasticity of the arterial walls. This can increase the risk of various cardiovascular diseases, such as hypertension, atherosclerosis, and heart disease. Additionally, smoking also promotes the production of free radicals and oxidative stress, further contributing to arterial damage and reduced elasticity.

The skin has various functions, including protection from infection and injury, sensation by detecting temperature, pressure, touch, and pain, and secretion of sebum to lubricate and protect the skin. However, excretion of sweat, which is 80% water and 20% salts, is not a function of the skin. Sweat is primarily produced by sweat glands and is involved in regulating body temperature.

Epithelial is not a gland of the endocrine system. Epithelial tissue covers the surfaces of organs, vessels, and cavities, and it does not secrete hormones like the glands of the endocrine system. The other options, Pineal, Adrenal, and Thyroid, are all glands that are part of the endocrine system and secrete hormones.

The given answer, "Functions as part of the immune system," is correct because the question asks for a function that is NOT part of the membranes. The other options, such as Meinges covering the brain and spinal cord, synovial membranes lining freely movable joint cavities, and serious membranes covering organs and lining body cavities, all describe functions that are part of the membranes.

The cellular level refers to the most basic structural and functional unit of life. It is the level at which chemicals combine to form the various molecules of the human body. Cells are the building blocks of all living organisms and are responsible for carrying out the essential functions necessary for life. They are capable of reproducing, obtaining and utilizing energy, and responding to their environment. At the cellular level, complex processes such as metabolism, growth, and differentiation occur, allowing organisms to function and maintain homeostasis.

The spleen is an organ located in the upper left side of the abdomen. It plays a crucial role in filtering the blood and removing old or damaged red blood cells. If the spleen is ruptured, it can lead to severe internal bleeding, which can be life-threatening. The spleen is highly vascular, meaning it has a lot of blood vessels, making it more prone to rupture in cases of trauma or certain medical conditions. Therefore, if the spleen is ruptured, it can prove fatal.

The correct answer is Sionatrial. The node that acts as the 'pacemaker' in the heart is called the sinoatrial (SA) node. It is located in the right atrium and is responsible for initiating the electrical signals that regulate the heartbeat. These signals cause the myocardium to contract and pump blood throughout the body.

During diastole, the heart relaxes and refills with blood. This is the phase of the cardiac cycle when the heart chambers are not contracting but rather preparing for the next contraction. The relaxation allows the chambers to fill with oxygenated blood returning from the lungs (in the left side of the heart) or deoxygenated blood returning from the body (in the right side of the heart). This refilling of blood is essential for the heart to pump efficiently and maintain adequate blood flow throughout the body.

Osteoblasts are the bone building cells responsible for the formation and mineralization of bone tissue. They are involved in the production of new bone and play a crucial role in bone growth, remodeling, and repair. Osteoblasts produce and secrete proteins and other substances that form the organic matrix of bone, which is then mineralized with calcium and other minerals to create solid bone tissue.

The ureters are the tubes through which urine leaves the kidneys and travels to the bladder. They connect the kidneys to the bladder and play a crucial role in the urinary system by transporting urine from the kidneys, where it is produced, to the bladder, where it is stored until it is eliminated from the body.

There are 12 ribs in the human body.

Short bones are characterized by having a body approximately as wide as they are long. This means that the length and width of these bones are roughly the same. Short bones are typically found in areas where strength and stability are required, such as the wrists and ankles. Unlike long bones, which have a longer body, short bones have a more compact shape. They do not fall into previous categories due to their non-uniform shape, making them distinct from other bone types.

The peripheral nervous system is made up of two main components: the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and sensory information, while the autonomic nervous system controls involuntary functions such as heart rate, digestion, and breathing. Therefore, the correct answer is somatic and autonomic.

The correct answer is "Secretes bodily products such as sebum, or hormones such as insulin." Glandular tissue is responsible for producing and secreting substances such as sebum, sweat, saliva, and hormones. These secretions play important roles in various bodily functions, such as lubricating the skin, regulating body temperature, aiding in digestion, and maintaining hormonal balance.

Capillaries are the smallest of all blood vessels and are one cell thick, allowing for gaseous exchange through diffusion. They also allow nutrients, oxygen, and fluids to pass into tissues, while carbon dioxide waste minerals and fluids pass out. However, capillaries do not serve as the connection between the somatic and autonomic systems. The somatic and autonomic systems are connected through other structures such as nerves and ganglia.

Lymphoid tissue functions as part of the immune system to help protect the body from infection. It is responsible for producing and storing white blood cells, which play a crucial role in fighting off pathogens and foreign substances in the body. Lymphoid tissue includes organs such as the spleen, thymus, and lymph nodes, as well as aggregates of lymphocytes found in various parts of the body, such as tonsils and Peyer's patches in the intestines. This tissue type is essential for the body's defense against infections and maintaining overall immune function.

Mitochondria are known as the powerhouse of the cell because they are responsible for converting energy from food molecules into ATP (adenosine triphosphate), which is the main source of energy for cellular processes. They have their own DNA and are capable of reproducing independently within the cell. Mitochondria have a unique structure with an outer membrane and an inner membrane, which allows them to carry out cellular respiration and produce ATP through a process called oxidative phosphorylation. Therefore, mitochondria play a crucial role in energy production within the human cell.

Blood vessels can be categorized based on their size and function. Capillaries are the smallest blood vessels, with a diameter that allows for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. Veins are larger in diameter than capillaries and are responsible for carrying deoxygenated blood back to the heart. Arteries are the largest blood vessels and have thick, muscular walls that carry oxygenated blood away from the heart to the rest of the body. Therefore, the correct order from smallest to biggest size wise is Capillaries > Veins > Arteries.

Only one nerve is needed for a myocardium contraction. The nerve responsible for initiating the contraction is the sinoatrial (SA) node, located in the right atrium of the heart. The SA node generates electrical impulses that spread through the myocardium, causing it to contract and pump blood. Therefore, only one nerve is required for this process.

The correct answer is "Mouth, Oesophagus, Stomach, Small intestine, Large Intestine, Rectum." This is the correct sequence of organs through which food passes in the digestive system. The mouth is where food enters the body and is chewed, the oesophagus is the tube that carries food from the mouth to the stomach, the stomach breaks down food further with digestive juices, the small intestine absorbs nutrients from the broken-down food, the large intestine absorbs water and electrolytes, and the rectum stores and eliminates waste.

The cardiovascular system is responsible for transporting carbon dioxide and waste products throughout the body for removal. This is achieved through the circulation of blood, which carries these waste substances from the cells to the organs responsible for their elimination, such as the lungs and kidneys. This function ensures that the body's cells receive a fresh supply of oxygen and nutrients while efficiently removing waste materials.

The small intestine is the main area of absorption of nutrients into the bloodstream. It is where the majority of digestion and absorption of nutrients takes place. Enzymes produced by the liver, gall bladder, and pancreas help break down food and aid in the absorption of nutrients into the bloodstream. The small intestine has a large surface area due to its villi and microvilli, which increases its capacity for absorption.

Ligaments are tough, fibrous dense connective tissues that help to stabilize a joint and prevent unwanted movement. They connect bones to other bones, providing stability and support. Tendons, on the other hand, connect muscles to bones and are responsible for transmitting the force generated by the muscles to the bones, allowing movement. Myofibrils and sarcomeres are structures found within muscle cells and are involved in muscle contraction, but they do not directly stabilize joints.

Glandular tissue is the correct answer because it is responsible for secreting bodily products such as sebum and hormones like insulin. This tissue is specialized to produce and release substances that are essential for various physiological processes in the body. Glandular tissue can be found in various organs such as the pancreas, which secretes insulin, and the sebaceous glands, which secrete sebum to lubricate the skin and hair.

An organ is the fourth biggest structural organization of the human body. It is a collection of tissues that work together to perform a specific function. Organs are larger and more complex than tissues, systems, and organismal levels of organization. They are made up of different types of tissues that have specialized functions, such as the heart, lungs, and liver. Organs work together within systems to maintain the overall function and homeostasis of the body.

Cardiac muscle is the correct answer because it is striated in appearance, meaning it has a striped or banded pattern. Additionally, it is involuntary, meaning it is not under conscious control. Cardiac muscle is found in the walls of the heart and is responsible for the contraction and pumping of blood throughout the body. Smooth muscle, on the other hand, is also involuntary but lacks striations, while skeletal muscle is striated but is under voluntary control.

The Parathyroid gland is responsible for regulating calcium levels in the blood. It does this by releasing parathyroid hormone (PTH), which stimulates the release of calcium from the bones into the bloodstream, increases calcium absorption from the intestines, and decreases calcium excretion by the kidneys. This helps to maintain the appropriate levels of calcium in the blood, which is crucial for various physiological processes such as muscle function, nerve transmission, and bone health.

The correct answer is the Chemical Level. The human body is organized in a hierarchical manner, starting from the smallest units to the largest. The Chemical Level refers to the level of organization where atoms and molecules interact to form complex chemical compounds. It is the most basic level of organization and serves as the foundation for all other levels. At this level, various chemical reactions occur, allowing for the functioning of cells, tissues, and organs.

The pineal gland is responsible for producing the hormone melatonin, which helps regulate sleep patterns. Melatonin is released in response to darkness and helps to promote sleep by signaling to the body that it is time to rest. This hormone plays a crucial role in maintaining a normal sleep-wake cycle and is often used as a supplement to treat sleep disorders such as insomnia. The other glands listed (pituitary gland, adrenal gland, and pancreas) do not produce melatonin and are responsible for other functions in the body.

The statement that is true about systemic circulation is "Deoxygenated blood from the body tissues to the heart." Systemic circulation is the part of the circulatory system that carries oxygenated blood from the heart to the body tissues and returns deoxygenated blood back to the heart. This is in contrast to pulmonary circulation, which carries deoxygenated blood from the heart to the lungs to be oxygenated.

The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for secretion. It receives proteins from the endoplasmic reticulum, modifies them by adding sugars or lipids, and then sorts and packages them into vesicles for transport to their final destination within or outside the cell. This process ensures that proteins are properly modified and targeted to their intended locations, allowing for efficient secretion and functioning of the cell.

The correct answer is Diaphysis. The diaphysis is the name given to the bone shaft within the structure of a long bone. It is the long, cylindrical, main portion of the bone that provides support and strength. The diaphysis is composed mainly of compact bone and contains the medullary cavity, which houses bone marrow.

The correct answer is Epiphysis. The epiphysis refers to the end of a long bone that forms the joint. It is covered with articular cartilage and helps to provide stability and support to the joint. The epiphysis also contains red bone marrow, which is responsible for producing blood cells. The other options mentioned in the question, such as epiphyseal plates, diaphysis, and medullary cavity, are not the correct names for the end of a long bone that forms the joint.

The order of the structural organization of the human body from smallest to biggest is as follows: chemical, cellular, tissue, organ, system, organismal. This means that the smallest level of organization is the chemical level, followed by the cellular level, where cells are formed. Cells then come together to form tissues, which in turn make up organs. Organs work together to form systems, and all of these systems together make up the organismal level, which represents the entire human body.

The correct answer is motor because motor nerves carry information from the central nervous system (CNS) to the muscles and glands, allowing for voluntary movement and control. These nerves transmit signals that initiate muscle contractions or glandular secretions in response to commands from the CNS. Sensory nerves, on the other hand, convey information from the body's sensory receptors to the CNS, allowing for the perception of touch, pain, temperature, and other sensations. Parasymphatic and somatic are not types of nerves but refer to different divisions of the autonomic nervous system and the body's voluntary control, respectively.

Arteries do not have smaller branches called venules. Venules are actually small blood vessels that collect blood from capillaries and carry it back to the veins. Arteries are muscular tubes lined by smooth muscle tissue that transport blood away from the heart. The coronary artery does supply oxygen to the myocardium, which is the muscular tissue of the heart.

The correct answer is "Right Atrium > Right Ventricle > Left Atrium > Left Ventricle". This is the correct order of the flow of blood from the vena cava. The vena cava carries deoxygenated blood from the body to the right atrium of the heart. From the right atrium, the blood flows into the right ventricle. The right ventricle then pumps the blood into the pulmonary artery, which carries it to the lungs for oxygenation. After oxygenation, the blood returns to the heart through the pulmonary veins, entering the left atrium. From the left atrium, the blood flows into the left ventricle, which then pumps oxygenated blood out to the rest of the body.

The function of an osteoblast is to build new bone. Osteoblasts are responsible for the synthesis and secretion of the proteins and other components needed to form new bone tissue. They play a crucial role in bone development, growth, and repair. Osteoblasts work in conjunction with osteoclasts, which are responsible for bone resorption, to maintain a balance in the remodeling and restructuring of bone tissue.

Deoxygenated blood is transported from the heart to the lungs because pulmonary circulation is responsible for carrying deoxygenated blood from the right side of the heart to the lungs, where it picks up oxygen and gets rid of carbon dioxide. This oxygenation process occurs in the lungs, and the oxygenated blood is then returned to the left side of the heart to be pumped to the rest of the body.

The cardiovascular system is responsible for the transportation of oxygen, nutrients, hormones, and waste products throughout the body. It also helps regulate body temperature by redistributing heat. Additionally, it provides protection by clotting blood to prevent excessive bleeding. However, storage is not a function of the cardiovascular system.

Increase mental alertness is a sympathetic response to the psychological effects of sports massage because it activates the sympathetic nervous system, which is responsible for the body's "fight or flight" response. This response increases alertness, focus, and readiness for physical activity. It can help athletes perform at their best by enhancing their cognitive function and reaction time.

There are two types of nerves in the human body. These are sensory nerves and motor nerves. Sensory nerves transmit information from the senses to the brain, allowing us to perceive and interpret our surroundings. Motor nerves, on the other hand, carry signals from the brain to the muscles, enabling movement and coordination.

The cardiovascular system is responsible for the circulation of blood throughout the body. One of the functions of the cardiovascular system is to transport oxygen, nutrients, and hormones to the cells, while also removing waste products, including carbon dioxide. However, the statement that is true of the cardiovascular system is that it circulates blood which contains white blood cells to fight infection. White blood cells are a crucial component of the immune system and are responsible for defending the body against pathogens and foreign substances.

The lymphatic system is a network of vessels and lymph nodes that play a crucial role in the immune system. Lymph nodes are small, bean-shaped structures that filter lymph fluid and contain immune cells. They are found throughout the body, including the neck, armpits, groin, and abdomen. While the exact number of lymph nodes can vary from person to person, it is estimated that there are approximately 600 lymph nodes in the human body.

An eccentric muscle contraction occurs when the muscle lengthens as it contracts. This type of contraction is typically involved in the control or deceleration of a movement. In contrast, a concentric contraction occurs when the muscle shortens as it contracts. Isometric contraction refers to a contraction where the muscle length remains constant, and isotonic contraction refers to a contraction where the muscle tension remains constant. Therefore, the correct answer is eccentric.

The central nervous system is responsible for receiving and storing information, collating information and decision making, and initiating instructions for bodily activities. However, helping maintain homeostasis is not a part of the central nervous system's functions. Homeostasis refers to the body's ability to maintain a stable internal environment, which is regulated by other systems such as the endocrine system and the autonomic nervous system.

Epithelial tissue functions as a covering for the body surface, lining most cavities, and forming glands. It is made up of closely packed cells that are tightly connected to each other, providing a protective barrier for the body. Epithelial tissue is found in the skin, respiratory tract, digestive tract, and many other organs and structures throughout the body. It also plays a role in secretion, absorption, and sensory perception. Glandular tissue, lymphoid tissue, and nervous tissue have different functions and are not primarily responsible for covering the body surface or lining cavities.

The lymphatic system is a network of vessels that transport lymph fluid throughout the body. This system includes a large number of lymphatic vessels, which vary in size and function, and help in maintaining fluid balance, immune responses, and the removal of waste products.

Bone growth takes place at the epiphyseal plate. The epiphyseal plate is a layer of cartilage located at the ends of long bones in children and adolescents. It is responsible for the lengthening of bones during the growth process. The plate contains specialized cells called chondrocytes that divide and multiply, leading to the production of new cartilage. As the cartilage cells mature, they are replaced by bone cells, resulting in bone growth. Once the growth process is complete, the epiphyseal plate closes and is replaced by solid bone.

Synovial joints are characterized by the presence of a synovial cavity, articular cartilage, a synovial membrane, and a joint capsule. They allow for a wide range of movements, and examples of synovial joints include hinge joints, ball-and-socket joints, and saddle joints.

"Vertebrae" refers to the individual bones that make up the vertebral column or spine. While the spine allows for various types of movement, it is not considered a synovial joint itself. Instead, it consists of a series of individual vertebrae, each with its own characteristics and joint connections, such as intervertebral discs and facet joints.

The internal intercostal muscles are not used in inhalation. Inhalation is the process of taking in air, and it is primarily facilitated by the contraction and flattening of the diaphragm muscle. The diaphragm moves downward, creating more space in the chest cavity and allowing the lungs to expand. The scalenes and sternocleidomastoid muscles also assist in inhalation by lifting the ribcage and expanding the chest further. However, the internal intercostal muscles are involved in exhalation, not inhalation. They help to compress the ribcage and decrease the volume of the chest cavity during exhalation.

The axon is the conducting unit of the nerve cell that carries electrical signals from the cell body to other cells. It is responsible for transmitting information and impulses to other neurons, muscles, or glands. Axons are long, slender projections that can extend over long distances, allowing for efficient communication within the nervous system. They are covered by a myelin sheath, which helps to insulate and speed up the conduction of electrical signals. Overall, the axon plays a crucial role in the transmission of messages throughout the nervous system.

Troponin is the correct answer because it is the term given to the complex of proteins that are attached to tropomyosin. Troponin is a key regulatory protein in muscle contraction and works together with tropomyosin to control the interaction between actin and myosin filaments. It plays a crucial role in the regulation of muscle contraction by allowing or preventing the binding of myosin to actin. The other options, actin, myosin, and sarcoplasmic reticulum, are not specifically associated with the complex of proteins attached to tropomyosin.

Muscle contraction requires the presence of ATP, which is the primary energy source for muscle cells. ATP is broken down into ADP and inorganic phosphate during muscle contraction, releasing energy that allows the muscle to contract. Calcium ions (Ca+) are also necessary for muscle contraction as they bind to proteins in the muscle fibers, triggering the sliding of actin and myosin filaments and resulting in muscle contraction. Therefore, adequate stores of ATP and calcium are required for muscle contraction to last.

Hydrochloric acid is used in the breakdown of food in the stomach. This acid is secreted by the gastric glands in the stomach lining and plays a crucial role in the digestion process. It helps to denature proteins, activate enzymes, and create an acidic environment that aids in the breakdown of food particles. Hydrochloric acid also acts as a defense mechanism by killing harmful bacteria that may be present in the food we consume.

Veins are not muscular tubes lined by skeletal muscle tissue. They are thin-walled blood vessels that carry deoxygenated blood back to the heart. While veins do contain smooth muscle in their walls, they lack the thick layer of skeletal muscle found in arteries.

The statement "Coronary artery supplies de-oxygenated blood to the myocardium (coronary circulation)" is not true. The coronary artery actually supplies oxygenated blood to the myocardium, which is the muscular tissue of the heart. It provides the heart muscle with the necessary oxygen and nutrients for it to function properly.

There are five classifications of bones.

The correct answer is Myosin. Myosin is the term given to the thick, contractile protein filament with protrusions known as myosin heads. It is responsible for the movement of muscle fibers by interacting with actin filaments. Myosin is a crucial component of muscle contraction and plays a vital role in muscle function.

The testes are responsible for the production of testosterone, a hormone that plays a crucial role in the growth of body hair. Testosterone stimulates the hair follicles, promoting the development of facial hair, chest hair, and pubic hair during puberty. Without the testes and the production of testosterone, the growth of body hair would be significantly reduced.

Lysosomes are cellular structures that contain enzymes responsible for breaking down and recycling obsolete components of the cell. They function as the cell's recycling center, digesting and disposing of damaged organelles, waste materials, and foreign substances. This process, known as autophagy, helps maintain the overall health and functionality of the cell by removing any unnecessary or dysfunctional components. Therefore, lysosomes are the correct answer as they play a crucial role in eliminating obsolete components of the cell.

The parathyroid gland is responsible for controlling calcium levels within the blood. It does this by producing parathyroid hormone (PTH), which helps regulate the amount of calcium in the blood. PTH acts on the bones, kidneys, and intestines to increase calcium levels when they are too low. This is important for maintaining proper bone health, nerve function, and muscle contractions.

The internal intercostals are not used in inhalation. During inhalation, the diaphragm contracts and moves downward, creating a vacuum that pulls air into the lungs. The scalenes and sternocleidomastoid muscles are accessory muscles that assist in inhalation by elevating the ribs and lifting the sternum, respectively. However, the internal intercostals are used during exhalation, as they help to depress the ribs and decrease the size of the thoracic cavity, forcing air out of the lungs.

The skin performs various functions including protection from infection and injury, formation of chemicals including vitamin D, and secretion of sebum to lubricate and protect the skin. However, excretion of sweat, which is 98% water and 2% salts, is not a function of the skin. Sweat is primarily excreted by sweat glands located in the skin, but the excretion itself is not a function of the skin.

Obesity carries the greatest risk of hypertension because excess body weight puts additional strain on the heart and blood vessels, leading to increased blood pressure. The accumulation of fat tissue can also disrupt the normal functioning of hormones and increase inflammation, both of which contribute to the development of hypertension. Additionally, obesity is often associated with other risk factors such as a sedentary lifestyle and poor dietary habits, further increasing the likelihood of developing high blood pressure.

The patella is a bone type that is classified as a sesamoid. Sesamoid bones are small, rounded bones that are embedded within tendons or joint capsules. They are commonly found in locations where a tendon passes over a joint, such as the patella which is located in the knee joint. The patella acts as a fulcrum for the quadriceps muscles, providing leverage and improving the efficiency of knee extension.

Ribosomes are responsible for combining amino acids to build proteins. Proteins are essential for the structure and function of cells, and ribosomes play a crucial role in protein synthesis. They read the genetic information encoded in mRNA molecules and use it to assemble amino acids in the correct order to form proteins. This process is known as translation, and it occurs in the cytoplasm of the cell. Therefore, the function of ribosomes is to facilitate the production of proteins, which are vital for various cellular processes.

Abdominal obesity carries the greatest risk according to studies of developing hypertension. This means that individuals with excess fat around their abdomen are more likely to develop high blood pressure. Studies have shown that abdominal obesity is strongly associated with an increased risk of hypertension, as it can lead to insulin resistance, inflammation, and hormonal imbalances that contribute to elevated blood pressure levels. Therefore, it is important to address and manage abdominal obesity to reduce the risk of developing hypertension.

Actin is the correct answer because it is a thin, contractile protein filament that contains active or binding sites. Sarcomere refers to the basic unit of muscle contraction, Myofibril refers to the thread-like structure within a muscle fiber, and Myosin refers to the motor protein that interacts with actin to generate muscle contraction.

The fourth biggest structural organization of the human body is an organ. An organ is a group of tissues that work together to perform a specific function. It is larger and more complex than a tissue, but smaller than a system. Examples of organs include the heart, liver, and lungs.

Cartilaginous joints are a type of joint where bones are connected by cartilage. These joints allow for slight movement and provide stability. Examples of cartilaginous joints include the joints between the vertebrae in the spine and the pubic symphysis in the pelvis. Fibrous joints do not allow for any movement, synovial joints are freely movable, and articular cartilage refers to the smooth, protective covering on the ends of bones in synovial joints. Therefore, the correct answer is cartilaginous as it describes a slightly movable joint.

Sports massage typically promotes vasodilation to both blood and lymphatic vessels, which increases blood flow and lymphatic drainage. This helps in delivering oxygen and nutrients to the muscles and removing waste products. Additionally, sports massage reduces neural stimulation of muscles, promoting relaxation and reducing muscle tension. It also helps in reducing the production of stress hormones, such as cortisol, promoting a state of relaxation and reducing stress. Vasoconstriction, on the other hand, would narrow the blood and lymphatic vessels, reducing blood flow and lymphatic drainage, which is not a desired effect of sports massage.

Sports massage does not directly influence the formation of collagen fibers. Collagen formation is primarily regulated by factors such as genetic predisposition, nutrition, and overall tissue health. Sports massage, however, can indirectly support collagen formation by promoting blood and lymphatic circulation, reducing muscle tension and stress hormones, and enhancing tissue recovery.

Oedema refers to the accumulation of excess fluid in the interstitial spaces of tissues, causing swelling. It is a condition characterized by the presence of tissue fluid in abnormal amounts. Therefore, oedema is the correct technical term for tissue fluid.

The endoplasmic reticulum is a cellular structure that provides a large surface area for chemical reactions to occur. It consists of a network of membranes that extends throughout the cytoplasm of the cell. The endoplasmic reticulum plays a crucial role in protein synthesis, lipid metabolism, and detoxification of drugs and toxins. Its extensive surface area allows for efficient and coordinated chemical reactions to take place, making it an essential organelle for cellular function.

Glandular tissue is responsible for secreting bodily productions such as sebum, which helps to lubricate the skin and hair, and hormones such as insulin, which regulates blood sugar levels. This function of glandular tissue is important for maintaining the overall health and functioning of the body.

A muscle or group of muscles that work together with the agonist to make movement is known as a synergist. The synergist muscles assist the agonist muscles by stabilizing joints and providing additional force to produce a desired movement. They help to coordinate and enhance the action of the agonist muscles, allowing for smooth and efficient movement. The antagonist muscles, on the other hand, have the opposite action to the agonist and work against it, while the fixator muscles stabilize the origin of the agonist muscle to allow for efficient movement. Actin is a protein involved in muscle contraction and is not directly related to the question.

The correct answer is Thoracic duct/Right lymphatic duct. The lymphatic system is responsible for draining excess fluid and waste products from the tissues. The thoracic duct is the largest lymphatic vessel in the body and carries lymph from the lower body and left side of the upper body. The right lymphatic duct, on the other hand, drains lymph from the right side of the upper body. Therefore, both the thoracic duct and right lymphatic duct are important lymphatic vessels in the body.

Tendons are tough, fibrous dense connective tissues that are contained within a sheath. They connect muscles to bones and help transmit the force generated by the muscles to the bones, allowing for movement. Ligaments, on the other hand, connect bones to other bones and do not have a sheath. Perimysium and endomysium are both connective tissues found within muscles, but they do not specifically have a sheath.

An organ is the correct answer because it is a structural organization that consists of two or more major tissue types that work together to perform specific functions for the body. Organs are composed of different tissues that are specialized for specific tasks, such as the heart, lungs, and liver. Each organ has a specific function and contributes to the overall functioning of the body.

The right lymphatic duct is a lymphatic vessel in the lymphatic system. It is responsible for draining lymph from the right upper limb, right side of the head and neck, and the right side of the thorax. It then empties into the right subclavian vein, returning the lymph to the bloodstream.

The skin secretes sebum, which is an oily substance that helps to lubricate and protect the skin. This secretion of sebum helps to keep the skin moisturized and prevent it from drying out. Additionally, sebum has antimicrobial properties and helps to maintain the acidic pH of the skin, which creates an environment that is unfavorable for the growth of harmful bacteria. Therefore, the secretion of sebum by the skin helps to keep the skin healthy and protected.
