  • 2. 

    The skin can appear yellowish along with the sclera of the eye due to ___________.

    • Jaundice

    • Ingested carrots

    • A really bad spray tan

    Correct Answer
    A. Jaundice
    Explanation
    Jaundice is a condition characterized by a yellowish discoloration of the skin and the whites of the eyes. It occurs when there is a buildup of bilirubin in the body, which is a yellow pigment produced when red blood cells are broken down. This buildup can be caused by various factors such as liver disease, hepatitis, or blockage of the bile ducts. The yellowish appearance of the skin and sclera is a result of the excess bilirubin depositing in these tissues. Ingested carrots and a bad spray tan would not cause this yellowish discoloration.

    The process whereby skin cells die and harden is called____________.

    • Granulosum

    • Carcenoma

    • Keratinization

    • Transformation

    Correct Answer
    A. Keratinization
    Explanation
    Keratinization is the correct answer because it refers to the process in which skin cells undergo a series of changes, including cell death and hardening, to form a tough, protective layer on the surface of the skin. This process involves the production of a protein called keratin, which gives the skin its strength and durability. The other options, granulosum, carcenoma, and transformation, do not accurately describe the process of skin cell death and hardening.

    • Hemodialysis

    • Hematopoiesis

    • Hemolytic reaction

    • Hematocrit

    Correct Answer
    A. Hematopoiesis
    Explanation
    Hematopoiesis is the process of blood cell formation. It occurs in the bone marrow, where hematopoietic stem cells differentiate and mature into various types of blood cells, including red blood cells, white blood cells, and platelets. This continuous process ensures the production of new blood cells to replace old or damaged ones, maintaining the body's blood cell count and function. Hemodialysis is a medical procedure used to filter waste products from the blood in individuals with kidney failure. Hemolytic reaction refers to the destruction of red blood cells, and hematocrit is a measure of the volume of red blood cells in the blood.

    • Melanin

    • Dead keratinocytes

    • Apocrine

    • Dead leukocytes

    Correct Answer
    A. Dead keratinocytes
    Explanation
    The hair shaft is made up of dead keratinocytes. Keratinocytes are the main cells found in the outermost layer of the skin, known as the epidermis. These cells produce a tough protein called keratin, which forms the structural component of hair, nails, and the outer layer of the skin. As hair grows, the keratinocytes in the hair follicle are pushed up and out, becoming compacted and forming the hair shaft. Therefore, the hair shaft is composed of dead keratinocytes.

    A second degree burn is classified as a full thickness burn.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A second degree burn is not classified as a full thickness burn. A second degree burn affects both the epidermis and the dermis layers of the skin, but does not penetrate through the entire thickness of the skin. Full thickness burns, on the other hand, involve damage to all layers of the skin, including the underlying tissues. Therefore, the statement is false.

    Rate this question:

  • 26. 

    Burns that may not be painful due to sensory nerves having been destroyed are found in a _______ degree burn.

    • First

    • Second

    • Third

    Correct Answer
    A. Third
    Explanation
    Third degree burns are characterized by the destruction of all layers of the skin, including the sensory nerves. This means that the person may not experience pain in the affected area because the nerves responsible for transmitting pain signals have been damaged or destroyed. Therefore, burns that are not painful due to sensory nerve destruction are typically found in third degree burns.

    The _________ is the hollow chamber within the diaphysis of a long bone.

    • Medullary cavity

    • Trabeculae

    • Osteon

    • Epiphysis

    Correct Answer
    A. Medullary cavity
    Explanation
    The medullary cavity is the correct answer because it refers to the hollow chamber within the diaphysis of a long bone. This cavity is filled with bone marrow and plays a crucial role in the production and storage of blood cells. The trabeculae refer to the spongy bone tissue found at the ends of long bones, while an osteon is the basic structural unit of compact bone. The epiphysis, on the other hand, is the rounded end of a long bone.

    The vertebrae are considered ___________.

    • Sesamoid bones

    • Long bones

    • Irregular bones

    • Flat bones

    • Short bones

    Correct Answer
    A. Irregular bones
    Explanation
    The vertebrae are considered irregular bones because they do not fit into any of the other four categories of bone classification (long bones, short bones, flat bones, and sesamoid bones). Irregular bones have complex shapes and do not have a consistent length, width, or thickness. The vertebrae are irregular bones due to their unique structure and function in the vertebral column, which provides support and protection for the spinal cord.

    In childhood, Vitamin D deficiency can result in __________.

    • Osteomalacia

    • Rickets

    • Acromegaly

    • Fractures

    Correct Answer
    A. Rickets
    Explanation
    Vitamin D deficiency in childhood can lead to rickets. Rickets is a condition that affects the development of bones, causing them to become weak and soft. This can result in deformities, such as bowed legs or a curved spine. Rickets is primarily caused by a lack of vitamin D, which is essential for the absorption of calcium and phosphorus in the body. Without sufficient vitamin D, bones do not mineralize properly, leading to the characteristic symptoms of rickets.

    Rate this question:

  • 34. 

    The dermis is avascular?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The dermis is not avascular. It is a highly vascularized layer of the skin that contains blood vessels, lymphatic vessels, and nerve endings. These blood vessels supply oxygen and nutrients to the cells in the dermis and help regulate body temperature. The dermis also contains specialized structures such as hair follicles, sweat glands, and sebaceous glands, which are all supplied by blood vessels. Therefore, the statement that the dermis is avascular is incorrect.

    Explanation
    The periosteum is a dense connective tissue membrane that covers the entire surface of a bone except for the articular cartilage. It provides protection, nourishment, and assists in bone repair and growth. The periosteum also serves as an attachment point for tendons and ligaments.

    Rate this question:

  • 37. 

    _________ break down calcified matrix.

    • Osteoblasts

    • Osteoclasts

    • Osteocytes

    Correct Answer
    A. Osteoclasts
    Explanation
    Osteoclasts are cells that break down calcified matrix. They are responsible for bone resorption, which involves the breakdown of bone tissue. Osteoclasts secrete enzymes and acids that dissolve the mineralized matrix of bone, allowing for the release of calcium and other minerals. This process is essential for bone remodeling, repair, and maintenance of calcium homeostasis in the body. Osteoblasts, on the other hand, are responsible for bone formation, while osteocytes are mature bone cells that maintain bone tissue.

    Sebaceous glands are the correct answer because they are the glands that project into the hair follicles. These glands are responsible for producing and secreting sebum, an oily substance that helps to lubricate and waterproof the hair and skin. Sebaceous glands are found all over the body, except for the palms of the hands and the soles of the feet.

    Rate this question:

  • 39. 

    The flat bones of the skull and ribs are ___________.

    • Intramembranous bones

    • Endochondral bones

    Correct Answer
    A. Intramembranous bones
    Explanation
    Intramembranous bones refer to the type of bone development where bones are formed directly from mesenchymal tissue, without the presence of a cartilage model. The flat bones of the skull and ribs are examples of intramembranous bones because they are formed through the process of intramembranous ossification. This process involves the differentiation of mesenchymal cells into osteoblasts, which then lay down bone matrix to form the flat bones. Endochondral bones, on the other hand, are formed from a cartilage model and are not applicable to the flat bones of the skull and ribs.

    Rate this question:

  • 40. 

    All of these are steps in bone repair EXCEPT __________.

    • Formation of a hematoma at the break site

    • A bandaid is formed at the break site

    • Fibrocartilage and spongy bone form at the break site

    • Bony callus replaces fibrocartilage

    • Osteoclasts remove excess bony tissue

    Correct Answer
    A. A bandaid is formed at the break site
    Explanation
    The process of bone repair involves several steps. First, a hematoma is formed at the break site, which is a localized collection of blood. This hematoma provides a clotting framework for the subsequent steps. Next, fibrocartilage and spongy bone form at the break site to bridge the gap between the broken ends of the bone. This is followed by the formation of a bony callus, which replaces the fibrocartilage. Osteoclasts then come into play to remove excess bony tissue and remodel the bone. The formation of a bandaid at the break site is not a recognized step in bone repair.

    • Periosteum

    • Epiphysis

    • Diaphysis

    • Osteon

    Correct Answer
    A. Epiphysis
    Explanation
    The expanded portion at either end of a long bone is called the epiphysis. The epiphysis is responsible for the growth and development of the bone, as well as providing a surface for the attachment of tendons and ligaments. It contains a layer of cartilage called the articular cartilage, which helps to reduce friction and absorb shock at the joints. The epiphysis also contains red bone marrow, which is responsible for producing red blood cells, white blood cells, and platelets.

    The structural unit of compact bone is the _________, or Haversian system.

    • Endosteum

    • Osteon

    • Osteocyte

    • Epiphysis

    Correct Answer
    A. Osteon
    Explanation
    The structural unit of compact bone is called an osteon, or Haversian system. An osteon is composed of concentric layers of bone tissue called lamellae, which surround a central canal called the Haversian canal. This canal contains blood vessels, nerves, and connective tissue. The osteocytes, or bone cells, are located within small spaces called lacunae, found between the lamellae. The osteon provides strength and support to the bone, and allows for the transportation of nutrients and waste products through the Haversian canal.

    Most of the bones in the body, except for skull and rib bones, are ____________.

    • Intramembranous bones.

    • Endochondral bones.

    Correct Answer
    A. Endochondral bones.
    Explanation
    Most of the bones in the body, except for the skull and rib bones, are endochondral bones. This means that they develop from a cartilage model, which is gradually replaced by bone tissue during the process of ossification. Endochondral bones include the long bones of the limbs, such as the femur and humerus, as well as the bones of the hands, feet, and spine. The skull bones and rib bones, on the other hand, develop through a different process called intramembranous ossification, where bone tissue forms directly from mesenchymal cells.

    When heat is lost by being carried away by sweat this is called_______.

    • Radiation

    • Conduction

    • Convection

    • Dehydration

    • Evaporation

    Correct Answer
    A. Evaporation
    Explanation
    When heat is lost by being carried away by sweat, this process is called evaporation. Sweat is produced by our body to cool down when it gets hot. As the sweat on our skin evaporates, it takes away heat energy from our body, resulting in a cooling effect. This is why we feel cooler when we sweat.

    Trabeculae are found in cancellous bone which is also called _________.

    • Compact bone

    • Spongy bone

    • Short bone

    • Irregular bone

    Correct Answer
    A. Spongy bone
    Explanation
    Trabeculae are thin, branching structures that form a lattice-like network in cancellous bone. Cancellous bone, also known as spongy bone, is characterized by its porous and sponge-like appearance. It is found at the ends of long bones, in the vertebrae, and in other locations where bone strength and flexibility are required. Unlike compact bone, which is dense and solid, cancellous bone has a higher surface area and is filled with marrow. Trabeculae in cancellous bone provide support and help distribute forces across the bone, making it an ideal answer for the given question.

    The skin can appear orangish due to ___________.

    • Jaundice

    • Ingested carrots

    • A bad spray tan

    Correct Answer
    A. Ingested carrots
    Explanation
    Ingested carrots can cause the skin to appear orangish due to a condition called carotenemia. Carrots are rich in carotenoids, such as beta-carotene, which can accumulate in the body when consumed in large amounts. These carotenoids can give a yellow or orange tint to the skin, especially in areas with a high concentration of sweat glands, such as the palms and soles of the feet. This discoloration is harmless and temporary, and it can be resolved by reducing carrot intake.

    The suture that separates the parietal bones is called the ____________.

    • Lambdoid suture

    • Sagittal suture

    • Coronal suture

    • Squamous suture

    Correct Answer
    A. Sagittal suture
    Explanation
    The suture that separates the parietal bones is called the sagittal suture. The sagittal suture is a dense, fibrous joint that runs along the midline of the skull, from the front to the back. It connects the two parietal bones and helps to provide structural support and stability to the skull.
