    ____________ is the most dangerous type of skin cancer.

    Correct Answer
    Melanoma
    Explanation
    Melanoma is the most dangerous type of skin cancer because it develops in the cells that produce melanin, which gives color to the skin, hair, and eyes. It is more likely to spread to other parts of the body if not detected and treated early. Melanoma can be caused by excessive exposure to UV radiation from the sun or tanning beds, a history of sunburns, family history of melanoma, and having many moles or atypical moles. It is crucial to protect the skin from sun exposure, regularly check for any changes in moles or skin, and seek medical attention if any suspicious growths are noticed.

    Correct Answer
    Alopecia
    Explanation
    Alopecia refers to hair thinning that occurs in both men and women. It is a condition that can lead to partial or complete hair loss on the scalp or other parts of the body. The term "alopecia" is used as a general term to describe various types of hair loss, including male and female pattern baldness. This condition can be caused by various factors such as genetics, hormonal changes, autoimmune disorders, and certain medical treatments.

  • 5. 

    Which cells of the epidermis produce fibrous protein keratin?

    • Melanocytes

    • Langerhans' Cells

    • Merkel cells

    • None of the above

    Correct Answer
    A. None of the above
    Explanation
    The cells of the epidermis that produce fibrous protein keratin are called keratinocytes. Melanocytes produce the pigment melanin, Langerhans' cells are involved in immune responses, and Merkel cells function as touch receptors. Therefore, none of the above options are correct.

    Rate this question:

  • 6. 

    Which layer accounts for 3/4 of the epidermal thickness?

    • Corneum

    • Basale

    • Spinosum

    • Lucidium

    Correct Answer
    A. Corneum
    Explanation
    The corneum layer is the outermost layer of the epidermis and is responsible for providing protection to the underlying layers. It is composed of dead skin cells that are constantly being shed and replaced. This layer is thick and accounts for approximately 3/4 of the total epidermal thickness.

    Rate this question:

  • 7. 

    What type of burn only affects the epidermis and upper regions of the dermis?

    Correct Answer
    2nd degree, second degree, 2 degree
    Explanation
    A second-degree burn, also known as a partial-thickness burn, only affects the epidermis (the outermost layer of the skin) and the upper regions of the dermis (the layer beneath the epidermis). This type of burn typically causes redness, blistering, and pain. It does not penetrate deeper into the skin layers like a third-degree burn. Therefore, the correct answer is 2nd degree, second degree, or 2 degree.

    Rate this question:

  • 8. 

    Which glands are not active until puberty?

    Correct Answer
    Apocrine glands, apocrine glands, apocrine sweat glands
    Explanation
    The glands that are not active until puberty are the apocrine sweat glands. These glands are part of the skin's larger sweat gland system and are located in areas abundant with hair follicles, such as the underarms, groin, and scalp. Apocrine glands remain largely inactive until hormonal changes trigger their development and activity during puberty. They produce a thicker, milky sweat that, when broken down by bacteria on the skin, can lead to the characteristic body odor associated with adolescents and adults.

    Correct Answer
    Epidermis, epidermis
    Explanation
    The epidermis is the thin, outermost layer of the skin, composed primarily of epithelial cells. It acts as the body's first line of defense, protecting against water loss, pathogens, and UV radiation. The epidermis also contains melanocytes, cells that produce melanin, the pigment responsible for skin color.
