    What type of burn damages the epidermis and part of the dermis?

    • First-degree

    • Second-degree

    • Third-degree

    • Fourth-degree

    Correct Answer
    A. Second-degree
    Explanation
    A second-degree burn damages the epidermis (the outer layer of skin) and part of the dermis (the layer beneath the epidermis). This type of burn is characterized by redness, blistering, and pain. The damage extends beyond the top layer of skin, affecting the deeper layers as well.

    Which of the following allows movement of muscles and joints and maintains normal skin tension.

    • Elastic fibers

    • Collagen fibers

    • Tactile cells

    • Dermal papillae

    Correct Answer
    A. Elastic fibers
    Explanation
    Elastic fibers are responsible for allowing movement of muscles and joints and maintaining normal skin tension. These fibers provide elasticity and flexibility to tissues, allowing them to stretch and recoil. They are particularly important in the skin, where they help maintain its firmness and resilience. Collagen fibers, on the other hand, provide strength and support to tissues, but do not contribute significantly to elasticity. Tactile cells are responsible for detecting touch sensations, while dermal papillae are involved in the formation of fingerprints and provide nourishment to the epidermis.

  • 4. 

    Which of the following is NOT found in the epidermis?

    • Squamous epithelial cells

    • Langerhans cells

    • Red blood cells

    • Melanocytes

    Correct Answer
    A. Red blood cells
    Explanation
    Red blood cells are not found in the epidermis. The epidermis is the outermost layer of the skin and primarily consists of squamous epithelial cells. Langerhans cells are a type of immune cell found in the epidermis that play a role in the immune response. Melanocytes are responsible for producing melanin, the pigment that gives color to the skin. However, red blood cells are not present in the epidermis as they are found in the bloodstream and are responsible for carrying oxygen to different parts of the body.

    What is the most dangerous form of skin cancer?

    • Basal cell carcinoma

    • Squamous cell carcinoma

    • Karposi's sarcoma

    • Melanoma

    Correct Answer
    A. Melanoma
    Explanation
    Melanoma is the most dangerous form of skin cancer because it develops in the melanocytes, the cells that produce melanin, which gives color to the skin. Melanoma tends to spread quickly to other parts of the body, making it more difficult to treat and potentially life-threatening. It is crucial to detect melanoma early to increase the chances of successful treatment and prevent its spread.

    Rate this question:

  • 6. 

    Which of the following is NOT a protective function of the skin?

    • Melanocytes protect from UV radiation

    • As a covering, it keeps pathogens out

    • The oily secretions allow bacteria to grow

    • Langerhans cells phagocytize pathogens

    Correct Answer
    A. The oily secretions allow bacteria to grow
    Explanation
    The oily secretions of the skin, known as sebum, actually have antimicrobial properties that help to inhibit the growth of bacteria. Therefore, it is incorrect to say that the oily secretions allow bacteria to grow.

    Which layer of the epidermis protects from abrasion and is only found in thick skin?

    • Stratum basale

    • Stratum lucidum

    • Stratum spinosum

    • Stratum corneum

    Correct Answer
    A. Stratum lucidum
    Explanation
    The stratum lucidum is the layer of the epidermis that protects from abrasion and is only found in thick skin. It is a clear, translucent layer that is located between the stratum granulosum and the stratum corneum. This layer provides additional protection to the skin by adding an extra barrier against friction and wear. It is primarily composed of dead skin cells that have lost their nuclei and other organelles, making it less susceptible to damage.

  • 8. 

    Tactile cells detect sensations of 

    • Pain

    • Temperature

    • Touch

    • All of the above

    Correct Answer
    A. Touch
    Explanation
    Tactile cells are responsible for detecting sensations of touch. These specialized cells are located in the skin and help us perceive different textures, pressures, and vibrations when we come into contact with objects or surfaces. Tactile receptors are particularly sensitive to mechanical stimuli, allowing us to feel and interpret the world around us through the sense of touch.

    The dermal papillae anchor the dermis to the hypodermis.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The dermal papillae do not anchor the dermis to the hypodermis. Rather, they play a role in increasing the surface area between the dermis and epidermis, which helps with nutrient exchange and enhances grip. The anchor between the dermis and hypodermis is provided by collagen fibers and adipose tissue.

    Rate this question:

  • 10. 

    What type of skin gland secretes sweat?

    • Sebaceous gland

    • Sudoriferous gland

    • Ceruminous gland

    • Mammary gland

    Correct Answer
    A. Sudoriferous gland
    Explanation
    The correct answer is sudoriferous gland. Sudoriferous glands are responsible for secreting sweat. This type of gland is found all over the body and helps regulate body temperature by producing sweat, which then evaporates and cools the skin. Sebaceous glands, on the other hand, secrete oil and are responsible for lubricating the skin and hair. Ceruminous glands produce earwax, while mammary glands produce milk in females.
