5. Appendicular skeletal system comprises all of the following EXCEPT : 

Explanation

The appendicular skeletal system consists of the bones that make up the limbs, including the arms and leg bones. It also includes the bones of the wrists and ankles, as well as the shoulder and hip bones. However, the cranial and facial bones are not part of the appendicular skeletal system. They belong to the axial skeletal system, which includes the bones of the head, neck, and trunk.

Submit
6. The term ______ refers to the shaft of a long bone

Explanation

The term "diaphysis" refers to the shaft of a long bone. It is the long, cylindrical, main portion of a bone between the two ends called epiphyses. The diaphysis is composed of compact bone tissue and contains the medullary cavity, which houses bone marrow. It provides support and stability to the bone and is responsible for transmitting forces during movement.

Submit
7. Which of the following is not one of the bones that makes up the hip bone?

Explanation

The acetabulum is not one of the bones that makes up the hip bone. The hip bone, also known as the coxal bone or os coxae, is made up of three bones: the ilium, ischium, and pubis. These three bones fuse together during development to form the hip bone. The acetabulum, on the other hand, is a cup-shaped socket on the lateral side of the hip bone that articulates with the head of the femur to form the hip joint.

Submit
8. Muscle enlargement due to over or excessive use is termed

Explanation

Hypertrophy is the correct answer because it refers to the enlargement or increase in size of muscle tissue due to excessive or overuse. This is a common response of muscles to intense exercise or strength training, where the muscle fibers increase in size and strength. Atrophy, on the other hand, refers to the wasting or shrinkage of muscle tissue due to lack of use or inactivity. Hyotrophy and dystrophy are not valid terms related to muscle enlargement.

Submit
9. Which joint permits the widest range of movement ?

Explanation

The ball and socket joint permits the widest range of movement. This is because it allows for movement in multiple directions, including rotation, flexion, extension, abduction, and adduction. The spherical head of one bone fits into the cup-like socket of another bone, allowing for a wide range of motion in different planes. This type of joint is found in the shoulder and hip, and it provides great mobility and stability.

Submit
10. Functions of the skeletal system include all EXCEPT : 

Explanation

The skeletal system is responsible for providing a body framework, supporting and protecting internal organs, and storing minerals. However, it does not generate body heat. Body heat is primarily produced by the muscular system through muscle contractions. The skeletal system plays a role in regulating body temperature by providing protection and support to the muscles, which are responsible for generating heat.

Submit
11. Shaking your head "no" is what type of movement

Explanation

Shaking your head "no" involves a rotational movement. This movement is a rotation because the head moves from side to side, pivoting around the neck joint. The other options, supination, abduction, and dorsiflexion, do not accurately describe the movement of shaking the head "no".

Submit
12. Signals generated by the nervous system are called 

Explanation

Signals generated by the nervous system are called nerve impulses. Nerve impulses are electrical signals that travel along the neurons, allowing communication between different parts of the body. These impulses are responsible for transmitting information and coordinating various bodily functions.

Submit
13. Moving a body part towards the midline of the body is called 

Explanation

Adduction is the correct answer because it refers to the movement of a body part towards the midline of the body. This movement is commonly seen when bringing the arms or legs closer to the body's center. Rotation refers to the movement around an axis, abduction refers to the movement away from the midline, and pronation refers to the rotation of the forearm so that the palm faces downward.

Submit
14. The _____ region of the verterbral column contains the largest number of bones 

Explanation

The thoracic region of the vertebral column contains the largest number of bones. This region is located in the middle of the spine and consists of 12 vertebrae. The thoracic vertebrae are larger and stronger compared to the cervical and lumbar vertebrae. They are connected to the ribs, forming the rib cage, which protects the vital organs in the chest. The thoracic region is responsible for supporting the upper body and providing stability to the spine.

Submit
15. The bone in the lower arm toward the thumb on which hand rotates is: 

Explanation

The bone in the lower arm towards the thumb that allows for rotation of the hand is called the radius. The radius is one of the two bones in the forearm, along with the ulna. It is located on the thumb side of the forearm and is responsible for the rotation of the hand and forearm. The ulna, on the other hand, is located on the pinky side of the forearm and is not involved in the rotation of the hand. The femur and humerus are bones found in the thigh and upper arm respectively, and are not relevant to the rotation of the hand.

Submit
16. The frontal bone of the skull is an example of a(n) _____ bone 

Explanation

The frontal bone of the skull is classified as a flat bone. Flat bones are thin and flat in shape, providing protection to underlying organs and supporting muscle attachment. The frontal bone forms the forehead and the upper part of the eye sockets, helping to protect the brain and the eyes. It is a good example of a flat bone because of its flat and broad surface, which allows for the attachment of muscles and provides a protective barrier.

Submit
17. The movement that is opposite of flexion is 

Explanation

Extension is the movement that is opposite of flexion. Flexion refers to the bending or decreasing the angle between two body parts, while extension refers to the straightening or increasing the angle between two body parts. Therefore, extension is the correct answer as it is the movement in the opposite direction of flexion.

Submit
18. During strenuous exercise 

Explanation

During strenuous exercise, the body may not be able to supply enough oxygen to the muscles, leading to an oxygen debt. This can result in the creation of lactic acid in the muscles. Therefore, both options a and b are correct.

Submit
19. Bone-building cells are called 

Explanation

Osteoblasts are bone-building cells that are responsible for the synthesis and secretion of the organic components of the bone matrix. They play a crucial role in bone formation and mineralization. Osteoblasts are derived from mesenchymal stem cells and are involved in the process of bone remodeling and repair. They are responsible for the deposition of new bone tissue and the regulation of bone mass. Osteoblasts also regulate the activity of osteoclasts, which are responsible for bone resorption. Osteocytes, on the other hand, are mature bone cells that are derived from osteoblasts and are involved in the maintenance and regulation of bone tissue. Chondrocytes, on the other hand, are cells found in cartilage tissue, not bone.

Submit
20. _________ are the bone- resorbing (eating) cells

Explanation

Osteoclasts are the bone-resorbing cells in the body. They are responsible for breaking down and removing old or damaged bone tissue. This process, known as bone resorption, helps in the remodeling and repair of bones. Osteoclasts play a crucial role in maintaining bone health and balance by working in coordination with osteoblasts, which are responsible for bone formation. Osteocytes are mature bone cells, while chondrocytes are cells found in cartilage tissue.

Submit
21. An abnormal side to side curve in the vertebral column is called

Explanation

Scoliosis is the correct answer because it refers to an abnormal side to side curve in the vertebral column. Lordosis refers to an excessive inward curvature of the spine, kyphosis refers to an excessive outward curvature of the spine, and convexities is not a term used to describe an abnormal curve in the vertebral column. Therefore, scoliosis is the most appropriate term for this condition.

Submit
22. Which of the following are cartilage cells? 

Explanation

Chondrocytes are cartilage cells. Osteoblasts are bone-forming cells, osteoclasts are bone-resorbing cells, and osteocytes are mature bone cells. However, chondrocytes are specifically responsible for producing and maintaining the cartilage matrix in the body. They are found in cartilage tissues and play a crucial role in the growth and repair of cartilage.

Submit
23. All of the following are characteristics of the muscles EXCEPT:

Explanation

Plasticity is not a characteristic of muscles. Contractibility refers to the ability of muscles to shorten and generate force, excitability refers to the ability of muscles to respond to stimuli, and elasticity refers to the ability of muscles to return to their original shape after being stretched. However, plasticity refers to the ability of the brain to change and adapt in response to experiences or learning.

Submit
24. Which bone condition occurs most frequently in postmenopausal women with claim deficiencies ?

Explanation

Osteoporosis is the correct answer because it is a bone condition that occurs most frequently in postmenopausal women with calcium deficiencies. It is characterized by a decrease in bone density and strength, making the bones more prone to fractures. Rickets is a condition that occurs in children due to a lack of vitamin D, causing weak and soft bones. Osteomalacia is a condition that occurs in adults due to a vitamin D deficiency, leading to softening of the bones. Paget's disease is a chronic bone disorder that affects older individuals, causing abnormal bone remodeling.

Submit
25. Strong fibrous band that attach skeletal muscles to bones are:

Explanation

Tendons are strong fibrous bands that attach skeletal muscles to bones. They are responsible for transmitting the force generated by the muscles to the bones, allowing movement and providing stability to the joints. Ligaments, on the other hand, connect bones to other bones, providing stability and preventing excessive movement. Aponeuroses are flat, sheet-like tendons that attach muscles to bones or other muscles, while fasciae are connective tissues that surround and support muscles, organs, and other structures. Therefore, the correct answer is tendons, as they specifically attach skeletal muscles to bones.

Submit
26. Moving a body part away from the midline of the body is called 

Explanation

Abduction is the correct answer because it refers to the movement of a body part away from the midline of the body. This movement typically occurs in the frontal plane, such as when lifting the arm out to the side or spreading the fingers apart. Pronation refers to the rotation of the forearm so that the palm faces downward, rotation refers to the turning movement of a body part around its own axis, and adduction refers to the movement of a body part toward the midline of the body.

Submit
27. How many bones are in the adult verterbral column?

Explanation

The adult vertebral column consists of 26 bones. These bones are called vertebrae and they are stacked on top of each other to form the spinal column. Each vertebra is separated by intervertebral discs, which provide cushioning and allow for movement. The vertebral column plays a crucial role in supporting the body, protecting the spinal cord, and allowing for flexibility and movement.

Submit
28. The layer made of tough fibrous tissue containing blood vessels, lymph nodes, and nerves that covers outer surface of the bone is:

Explanation

The periosteum is a layer of tough fibrous tissue that covers the outer surface of the bone. It contains blood vessels, lymph nodes, and nerves, which are important for the nourishment and sensation of the bone. The periosteum also plays a role in bone repair and growth. It serves as a protective covering for the bone and helps in the attachment of tendons and ligaments.

Submit
29. Muscle is connected to bone by 

Explanation

Tendons are the correct answer because they are the fibrous connective tissues that attach muscles to bones. They are responsible for transmitting the force generated by the muscle to the bone, allowing movement and providing stability to the joints. Ligaments, on the other hand, connect bones to other bones, while cartilage is a type of connective tissue found in joints and other structures. Epithelial tissue, although important for lining and protecting body surfaces, does not play a role in connecting muscles to bones.

Submit
30. Skeletal muscles are also referred to as 

Explanation

Skeletal muscles are referred to as "striated" because they have a striped appearance under a microscope due to the arrangement of their muscle fibers. They are also called "striped" because of this characteristic. Additionally, skeletal muscles are considered "voluntary" muscles because they are under conscious control. Therefore, the correct answer is "all these" because all of these terms accurately describe skeletal muscles.

Submit
31. Muscle hypertrophy

Explanation

Muscle hypertrophy refers to the increase in muscle size. This occurs when the muscles are subjected to resistance training or weightlifting exercises, causing microscopic damage to the muscle fibers. In response to this damage, the body repairs and rebuilds the muscle fibers, leading to an increase in size and strength. Endurance training, on the other hand, focuses on improving cardiovascular fitness and does not typically result in significant muscle hypertrophy. The other options, long periods of disuse and an increase in blood vessels to a muscle, do not accurately describe muscle hypertrophy.

Submit
32. ______ is the damage to muscle body or tear due to excessive use is called

Explanation

Strain refers to the damage or tear in the muscle body caused by excessive use. It occurs when muscles are stretched beyond their normal capacity or subjected to repetitive movements. This can happen during physical activities or sports that require intense muscle exertion. Sprain, on the other hand, refers to the damage or tear in the ligaments, while stress and tension are psychological or emotional conditions. Therefore, the correct answer is strain.

Submit
33. In extending the elbow, the 

Explanation

The triceps brachii muscle is responsible for extending the elbow joint. When the triceps brachii contracts, it causes the arm to straighten by pulling on the forearm bone. This muscle is considered the prime mover because it is the primary muscle responsible for generating the movement. The biceps brachii and brachiale muscles are not involved in extending the elbow and therefore cannot be considered the prime mover. The triceps brachii is not the antagonist in this case because it is the muscle that is actively producing the movement, not opposing it.

Submit
34. Which type of muscle tissue contains striations ?

Explanation

Both voluntary muscle and cardiac muscle contain striations. Voluntary muscle, also known as skeletal muscle, is under conscious control and is responsible for movement. It appears striated due to the arrangement of actin and myosin filaments. Cardiac muscle, found in the heart, is also striated but is involuntary. It contracts rhythmically to pump blood throughout the body. Smooth muscle, on the other hand, does not contain striations and is found in the walls of hollow organs such as the intestines and blood vessels.

Submit
35. In the bending of the elbow, the

Explanation

The biceps brachii is the prime mover in the bending of the elbow because it is primarily responsible for initiating and executing the movement. As the prime mover, it contracts and shortens, causing the forearm to flex and the elbow to bend. The triceps brachii, on the other hand, acts as a synergist, assisting the biceps brachii in the movement. The triceps brachii contracts to stabilize the arm and control the speed of the movement. The brachialis, although not mentioned in the question, is also a prime mover in elbow flexion, working in conjunction with the biceps brachii.

Submit
36. Shaking your head " yes " is what type of movement?

Explanation

Shaking your head "yes" involves a movement known as flexion. Flexion refers to the bending or decreasing the angle between two body parts. In this case, the head is being flexed forward and backward, creating the "yes" motion. Supination, rotation, and abduction are not applicable to this specific movement.

Submit
37. People with what condition go through episodes of "frenzied" bone resorption and bone growth?

Explanation

Paget's disease is a condition characterized by excessive bone resorption and abnormal bone growth. It causes the affected bones to become weak, enlarged, and deformed. This condition is typically seen in older individuals and can affect any bone in the body. Rickets, osteomalacia, and osteoporosis are conditions that also involve bone abnormalities, but they do not specifically cause episodes of frenzied bone resorption and growth as seen in Paget's disease.

Submit
38. Which bone of the skull does not contain sinuses?

Explanation

The zygomatic bone does not contain sinuses. Sinuses are air-filled cavities within the skull that help to lighten the weight of the skull and provide resonance to the voice. The frontal, sphenoid, and ethmoid bones all contain sinuses. The frontal bone contains the frontal sinus, the sphenoid bone contains the sphenoid sinus, and the ethmoid bone contains the ethmoid sinuses. Therefore, the zygomatic bone is the only bone listed that does not contain sinuses.

Submit
39. A genetic defect of muscle deterioration that appears in early childhood but becomes progressively serious with age and may leaf to death in teens or early twenties is

Explanation

Muscular dystrophy is the correct answer because it is a genetic defect that causes muscle deterioration. It typically presents in early childhood and worsens over time, often leading to death in the teenage years or early twenties. Muscular atrophy refers to the wasting away of muscle tissue, while muscular hypotrophy refers to underdevelopment of muscles. Muscular hypertrophy, on the other hand, refers to the increase in muscle size. Therefore, neither of these options accurately describes the condition described in the question.

Submit
40. Diarthrotic joints

Explanation

Diarthrotic joints are joints that allow the most movement in the body and are surrounded by a joint capsule. This means that both options A and C are correct. Diarthrotic joints are the most common type of joints in the body and include the shoulder, hip, and knee joints. They are characterized by their ability to move freely and their joint capsules provide stability and protection to the joint.

Submit
41. Ability of the muscle to respond to external stimuli is

Explanation

Excitability refers to the ability of a muscle to respond to external stimuli. When a muscle is stimulated by a nerve impulse, it is able to generate a response, such as contraction or relaxation. This response is essential for the muscle to perform its function, whether it is to move a body part or maintain posture. Therefore, excitability is the correct answer as it accurately describes the muscle's ability to respond to external stimuli.

Submit
42. The rings of calcified matrix that make up the haversian system are called 

Explanation

The rings of calcified matrix that make up the haversian system are called lamellae. Lamellae are concentric layers of bone tissue that surround the central canal of the haversian system. These layers are formed by osteoblasts and contain collagen fibers and mineral salts, providing strength and support to the bone. The lamellae also house the lacunae, which contain osteocytes, and are interconnected by canaliculi, allowing for the exchange of nutrients and waste between cells.

Submit
43. Which structure is not part of the lymphatic system?

Explanation

The pancreas is not part of the lymphatic system. The lymphatic system is a network of vessels, organs, and lymph nodes that help to maintain fluid balance in the body and play a role in the immune system. The tonsils, spleen, and thymus gland are all organs that are part of the lymphatic system and help to filter and produce lymphocytes, which are important for immune function. The pancreas, on the other hand, is an organ that is part of the digestive system and is responsible for producing enzymes and hormones, such as insulin, that help to regulate blood sugar levels.

Submit
44. When bone is partially bent like sap filled wooden stick but not separated, it is called:

Explanation

A greenstick fracture occurs when a bone is partially bent but not completely separated. It is commonly seen in children due to their more flexible bones. The term "greenstick" refers to the analogy of a young, green tree branch that can bend without breaking. In this type of fracture, the bone may crack on one side while the other side remains intact. Unlike an open or closed fracture where the bone is completely separated, a greenstick fracture is a partial break.

Submit
45. The muscle that initiates action or movement is 

Explanation

A prime mover is a muscle that initiates or produces a specific movement or action. It is responsible for generating the majority of the force needed to perform a particular movement. In other words, it is the main muscle that is primarily responsible for the desired action. This muscle contracts and shortens, causing the movement to occur. The prime mover works in coordination with other muscles, such as synergistic muscles, to produce smooth and efficient movements. The antagonistic muscles, on the other hand, work in opposition to the prime mover to control and stabilize the movement.

Submit
46. Muscles that are not striped and not under conscious control are 

Explanation

Smooth muscles are muscles that are not striped and not under conscious control. They are found in the walls of hollow organs such as the stomach, intestines, and blood vessels. Unlike skeletal muscles, which are voluntary and can be consciously controlled, smooth muscles are involuntary and work automatically to regulate various bodily functions. Cardiac muscles, on the other hand, are found only in the heart and are responsible for its contraction. Sphincter muscles are a type of smooth muscle that control the opening and closing of various body passages. Therefore, the correct answer is smooth muscles.

Submit
47. The structural unit of compact bone is called the 

Explanation

The structural unit of compact bone is called an osteon. An osteon consists of concentric rings of bone tissue called lamellae, which surround a central canal called the Haversian canal. The Haversian canal contains blood vessels, nerves, and connective tissue. Canaliculi are small channels that connect the lacunae (spaces between the lamellae) and allow for the exchange of nutrients and waste products between osteocytes (bone cells). Trabeculae, on the other hand, are found in spongy bone and form a lattice-like network. Therefore, the correct answer is osteon.

Submit
48. The place where a nerve joins a muscle is 

Explanation

A synapse is the place where a nerve joins a muscle. It is a small gap between the nerve ending and the muscle fiber, where communication occurs between the two. At the synapse, the nerve releases neurotransmitters, which are chemical messengers that transmit signals from the nerve to the muscle. These neurotransmitters bind to receptors on the muscle fiber, triggering a response and allowing for the transmission of nerve impulses to the muscle, leading to muscle contraction.

Submit
49. The triceps brachii and the biceps brachii

Explanation

The triceps brachii and the biceps brachii are antagonist to each other. This means that they have opposite actions. The triceps brachii is responsible for extending the forearm, while the biceps brachii is responsible for flexing the forearm. When one muscle contracts, the other muscle relaxes to allow for the desired movement. This antagonistic relationship allows for smooth and coordinated movement of the forearm.

Submit
50. Ensuring that young children have a sufficient amount of vitamin D in their diet will prevent 

Explanation

Rickets is a condition that occurs due to a deficiency of vitamin D, calcium, or phosphate. It primarily affects young children and causes weak and soft bones, leading to deformities and growth problems. Ensuring that young children have a sufficient amount of vitamin D in their diet is important to prevent rickets. Osteomalacia is a similar condition that affects adults, causing weak and soft bones. Osteoporosis is a condition characterized by low bone density and increased risk of fractures, commonly seen in older adults. Paget's disease is a chronic bone disorder that causes abnormal bone growth. None of these conditions are directly prevented by ensuring a sufficient amount of vitamin D in young children's diets.

Submit
51. Which type of muscle tissue specializes in contraction or shortening?

Explanation

All of the above is the correct answer because all three types of muscle tissue - cardiac, smooth, and striated - specialize in contraction or shortening. Cardiac muscle tissue is found in the heart and is responsible for the contraction of the heart muscles. Smooth muscle tissue is found in the walls of organs, blood vessels, and the digestive system, and it contracts to facilitate movement. Striated muscle tissue, also known as skeletal muscle, is attached to bones and allows for voluntary movements. Therefore, all three types of muscle tissue play a role in contraction or shortening.

Submit
52. The sutures are an examples of which type of joint?

Explanation

The sutures are fibrous joints found in the skull where the bones are tightly connected by fibrous connective tissue. These joints allow for very little or no movement, making them an example of synarthroses, which are immovable joints.

Submit
53. Which of the following is not a primary function of the muscular system?

Explanation

The muscular system has several primary functions, including movement, maintaining posture, and producing heat. However, the protection of internal organs not protected by bone is not a primary function of the muscular system. This is because the muscular system primarily focuses on providing movement and support to the body, rather than directly protecting internal organs. The protection of internal organs is mainly provided by other systems such as the skeletal system and the integumentary system.

Submit
54. Which of the following substances is not carried by the cardiovascular system?

Explanation

Lymph is not carried by the cardiovascular system. While the cardiovascular system is responsible for transporting blood throughout the body, lymph is carried by the lymphatic system. The lymphatic system is a separate network of vessels and organs that helps to circulate lymph, a clear fluid that contains white blood cells and waste products. Therefore, lymph is not carried by the cardiovascular system.

Submit
55. Which type of doing uses cartilage to connect bones?

Explanation

Amphiarthroses is the correct answer because this type of joint allows limited movement and uses cartilage to connect the bones. Diarthroses refers to freely movable joints, synarthroses refers to immovable joints, and none of the above is not the correct answer as amphiarthroses fits the description given.

Submit
56. Subluxation is another term for 

Explanation

Subluxation refers to a partial or incomplete dislocation of a joint, where the joint surfaces are not completely separated but are partially misaligned. This term is commonly used in the medical field to describe a joint that has moved out of its normal position but is not fully dislocated. Therefore, the correct answer is dislocation.

Submit
57. Another name for visceral muscle is ______ muscle

Explanation

Smooth muscle is another name for visceral muscle because it is found in the walls of internal organs and blood vessels. Unlike cardiac muscle (which is found in the heart) and skeletal muscle (which is voluntary and attached to bones), smooth muscle is involuntary and lacks striations or visible banding. It is responsible for the contraction and relaxation of organs such as the stomach, intestines, and blood vessels, allowing for the movement of substances and regulation of blood flow.

Submit
58. Bouchard nodes are common sign of which of the following conditions?

Explanation

Bouchard nodes are bony enlargements that develop on the middle joints of the fingers in individuals with osteoarthritis. Osteoarthritis is a degenerative joint disease that causes the breakdown of cartilage in the joints, leading to pain, stiffness, and the formation of these nodes. Sprains, strains, and dislocations are traumatic injuries that do not typically result in the development of Bouchard nodes.

Submit
59. What is the name of the spongy bone found inside flat bone?

Explanation

The correct answer is cancellous. Cancellous bone, also known as trabecular or spongy bone, is found inside flat bones. It has a lattice-like structure with small, interconnected spaces filled with bone marrow. This type of bone provides support and strength to the bone while also allowing for flexibility and the production of blood cells.

Submit
60. The parietal bones form which suture with the frontal bone?

Explanation

The parietal bones form the coronal suture with the frontal bone. The coronal suture is a dense, fibrous joint that connects the parietal bones to the frontal bone at the top of the skull. This suture allows for the growth and expansion of the skull during development.

Submit
61. Damage to a ligament results in which type of injury?

Explanation

When a ligament is damaged, it results in a sprain. A sprain occurs when a ligament is stretched or torn, usually due to excessive force or trauma to a joint. This can happen during activities such as sports or accidents. Symptoms of a sprain include pain, swelling, bruising, and difficulty moving the affected joint. Treatment typically involves rest, ice, compression, and elevation (RICE), as well as possible physical therapy or immobilization depending on the severity of the injury.

Submit
62. Strength training causes

Explanation

Strength training causes muscle hypertrophy, which refers to an increase in the size and strength of muscle fibers. When muscles are subjected to resistance exercise, such as lifting weights, it creates microscopic damage to the muscle fibers. In response to this damage, the body initiates a repair process that involves the synthesis of new proteins, leading to an increase in muscle fiber size. This adaptation is known as muscle hypertrophy and is responsible for the growth and development of muscles.

Submit
63. The storage function of the skeletal system refers to the storage of the 

Explanation

The storage function of the skeletal system refers to the storage of mineral calcium for the body. Calcium is an essential mineral that is stored in the bones and is important for maintaining bone density and strength. It is also involved in various other functions in the body, including muscle contraction, nerve function, and blood clotting. Therefore, the skeletal system plays a crucial role in storing and releasing calcium as needed to maintain overall health and function.

Submit
64. Which is the location in the long bone where hematopoiesis occurs?

Explanation

Hematopoiesis is the process of blood cell formation. The epiphysis is the rounded end of a long bone, which contains red bone marrow. Red bone marrow is responsible for hematopoiesis, producing red blood cells, white blood cells, and platelets. Therefore, the epiphysis is the location in the long bone where hematopoiesis occurs.

Submit
65. The hole in the center of the veterbrae the called the 

Explanation

The correct answer is vertebral foramen. 

Submit
66. Endurance training results in

Explanation

Endurance training involves activities that improve cardiovascular fitness, such as running, cycling, or swimming. These exercises increase the demand for oxygen and nutrients in the muscles, leading to the formation of new blood vessels, a process known as angiogenesis. This increase in blood vessels helps to deliver more oxygen and nutrients to the muscles, improving their endurance and overall performance. Therefore, the correct answer is "an increase in blood vessels to a muscle."

Submit
67. Which substance is stored in the muscles endoplasmic reticulum and then released when a nerve signal stimulates a muscle fiber?

Explanation

Calcium ions are stored in the muscles' endoplasmic reticulum and are released when a nerve signal stimulates a muscle fiber. This release of calcium ions plays a crucial role in muscle contraction. When the nerve signal triggers the release of calcium ions, they bind to proteins within the muscle fibers, initiating a series of events that ultimately lead to muscle contraction. Therefore, calcium ions are the substance stored in the muscles' endoplasmic reticulum and released during muscle stimulation.

Submit
68. Another name for a voluntary muscle is _______ muscle

Explanation

A voluntary muscle is a muscle that can be consciously controlled by the individual. The term "striated" refers to the appearance of muscle fibers under a microscope, which have a striped or striated pattern. Skeletal muscles, which are responsible for movement of the body, are both voluntary and striated. Therefore, both "striated" and "skeletal" can be used interchangeably to describe a voluntary muscle.

Submit
69. Another name for a compound fracture is a(n)  ________ fracture 

Explanation

Another name for a compound fracture is an open fracture. This term is used to describe a fracture where the bone breaks through the skin, creating an open wound. Unlike a closed fracture, where the bone remains within the skin, an open fracture poses a higher risk of infection and requires immediate medical attention.

Submit
70. All muscle in the body have antagonistic pairs EXCEPT 

Explanation

Both the orbicularis oris muscle and the diaphragm muscle do not have antagonistic pairs. The orbicularis oris muscle is responsible for puckering the lips and does not have a specific muscle that opposes its action. The diaphragm muscle is responsible for breathing and also does not have a specific muscle that opposes its action. In contrast, most other muscles in the body have antagonistic pairs, where one muscle contracts while the other relaxes to produce movement.

71. A progressive muscular weakness and paralysis by an unknown cause that in extreme causes may become fatal due to paralysis of respiratory muscle is:

Explanation

Myasthenia gravis is a condition characterized by progressive muscular weakness and paralysis. It is caused by an unknown factor and can become fatal if it affects the respiratory muscles. Muscular hypertrophy refers to an increase in muscle size, while muscular hypotrophy refers to a decrease in muscle size. Muscular atrophy refers to the wasting away or loss of muscle tissue. Therefore, myasthenia gravis is the correct answer as it best describes the given symptoms.

72. Which type of contraction can be seen in an isolated muscle but plays a minimal role in normal muscle activity?

Explanation

The correct answer is twitch because a twitch contraction refers to a single, brief contraction and relaxation of a muscle fiber. This type of contraction can be seen in an isolated muscle but plays a minimal role in normal muscle activity. Isometric contractions involve muscle tension without any change in muscle length, isotonic contractions involve muscle tension with a change in muscle length, and "techtonic" is not a recognized term in relation to muscle contractions.

73. Which of the following is not a form of inflammatory arthritis 

Explanation

Osteoarthritis is not a form of inflammatory arthritis. Unlike the other options listed, which are all types of arthritis that involve inflammation of the joints, osteoarthritis is a degenerative joint disease that occurs when the cartilage in the joints wears down over time. It is characterized by joint pain, stiffness, and limited range of motion, but it does not involve the same inflammatory processes as inflammatory arthritis.

74. If the muscles of a weightlifter and marathon runner were compared, the marathon runner would have

Explanation

The correct answer is "more mitchondria in each muscle cell". Marathon runners rely on aerobic metabolism for endurance, which requires a high amount of energy production. Mitochondria are responsible for producing energy in the form of ATP, so marathon runners have more mitochondria in their muscle cells to meet the demands of long-distance running. Weightlifters, on the other hand, rely more on anaerobic metabolism for short bursts of intense activity, so they have fewer mitochondria in their muscle cells.

Submit
75. The insertion of a muscle is the 

Explanation

The insertion of a muscle refers to the point where the muscle attaches to a bone or another muscle. The more movable muscle is the one that is responsible for generating the movement, while the less movable muscle is the one that provides stability or acts as an anchor. Therefore, the correct answer is "attachment to the more movable muscle" because it accurately describes the location of the insertion point.

Submit
76. If the muscles of a weightlifter and marathon runner were compared, the weightlifter would have

Explanation

The correct answer is larger muscle cells. This is because weightlifters engage in strength training which leads to hypertrophy, or an increase in the size of muscle cells. Marathon runners, on the other hand, engage in endurance training which does not typically result in significant muscle growth. Therefore, weightlifters would have larger muscle cells compared to marathon runners.

Submit
77. Which of these organs is a primary organ of the digestive system?

Explanation

The esophagus is a primary organ of the digestive system because it plays a crucial role in the process of digestion. It is a muscular tube that connects the throat to the stomach, allowing food to pass from the mouth to the stomach. The esophagus uses rhythmic muscle contractions called peristalsis to push food down into the stomach, where further digestion occurs. The liver and pancreas are also important organs in the digestive system, but they have secondary roles in the process.

Submit
78. The origin of a muscle is the 

Explanation

The origin of a muscle refers to its attachment point, and it is typically the more stationary bone. This is because muscles work by contracting and pulling on the bones they are attached to, causing movement. The more movable bone is usually the insertion point, where the muscle attaches and pulls towards during contraction. Therefore, the correct answer is "attachment to the more stationary bone."

Submit
79. The autoimmune muscle condition that is characterized by muscle weakness, especially in the face and throat , is called 

Explanation

Myasthenia gravis is an autoimmune muscle condition that is characterized by muscle weakness, particularly in the face and throat. It is caused by a breakdown in communication between nerves and muscles, leading to fatigue and difficulty in controlling muscle movement. This condition is not to be confused with fibromyositis, which is a condition characterized by inflammation and pain in the muscles and fibrous tissues. Myalgia refers to general muscle pain, while Duchenne muscular dystrophy is a genetic disorder that causes progressive muscle weakness and degeneration.

Submit
80. Tonic contractions

Explanation

Tonic contractions are continuous, low-level contractions of muscles that help maintain posture. These contractions provide the necessary support and stability to keep the body upright and balanced. They are different from phasic contractions, which are brief and intense contractions used for movements. Tonic contractions do not cause an oxygen debt in the body or produce large amounts of lactic acid. Therefore, the correct answer is that tonic contractions help maintain posture.
