    Tanning of the skin is caused by UVB rays, which affect the:

    • A.

      Melanocytes

    • B.

      Collagen fibers

    • C.

      Elastin fibers

    • D.

      Papillae

    Correct Answer
    A. Melanocytes
    Explanation
    Tanning of the skin is caused by UVB rays, which stimulate the production of melanin in the melanocytes. Melanocytes are responsible for producing the pigment melanin, which gives color to the skin. When exposed to UVB rays, melanocytes produce more melanin in an attempt to protect the skin from further damage. This increased production of melanin results in the darkening of the skin, commonly known as a tan.

    Skin contact with poison oak or poison ivy often causes:

    • A.

      Vesicles

    • B.

      Papules

    • C.

      Excoriation

    • D.

      Wheals

    Correct Answer
    A. Vesicles
    Explanation
    Skin contact with poison oak or poison ivy often causes vesicles, which are small fluid-filled blisters. These vesicles occur as a result of an allergic reaction to the urushiol oil found in these plants. When the oil comes into contact with the skin, it triggers an immune response, leading to the formation of vesicles. These blisters can be itchy, painful, and may ooze fluid. It is important to avoid scratching or popping the vesicles to prevent infection and further spread of the rash.

      Keloid

    Correct Answer
    A. Cyst
    Explanation
    A cyst is a type of primary lesion in which fluid, semifluid, or morbid matter is contained in a closed, abnormally developed sac. This means that the material is enclosed within a sac-like structure, which distinguishes it from other primary lesions such as papules, pustules, or keloids. A papule is a small, solid, raised bump on the skin, while a pustule is a small blister or pimple filled with pus. A keloid, on the other hand, is a type of raised scar that forms due to an overgrowth of collagen. Therefore, the correct answer is cyst.

    • A.

      Contact eith poison ivy

    • B.

      An insect bite

    • C.

      Scratching or scraping

    • D.

      The healing of an injury

    Correct Answer
    D. The healing of an injury
    Explanation
    A cicatrix is a slightly raised mark on the skin that forms after the healing of an injury. This process is known as cicatrization, where the body repairs and replaces damaged skin tissue. During the healing process, the body produces collagen, which can cause the scar to be slightly raised compared to the surrounding skin. This can occur after various types of injuries, such as cuts, burns, or surgical incisions. The formation of a cicatrix is a natural part of the body's healing response and can vary in appearance depending on factors such as the depth and location of the injury.
