____________ is the most dangerous type of skin cancer.
Correct Answer
MelanomaExplanation
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.Rate this question:

Which cells of the epidermis produce fibrous protein keratin?
- A.
Melanocytes
- B.
Langerhans' Cells
- C.
Merkel cells
- D.
None of the above
Correct Answer
D. None of the aboveExplanation
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:

Which glands are not active until puberty?
Correct Answer
Apocrine glands, apocrine glands, apocrine sweat glandsExplanation
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.Rate this question:

Hair is filamentous strands of __________________cells.
Correct Answer
dead keratinized, dead, keratinized, keratinised, dead keratinisedExplanation
Hair is composed of filamentous strands that are made up of dead keratinized cells.Rate this question:

Dilation (____________) and constriction (____________) occurs to regulate body temperature.
Correct Answer
cooling; warmingExplanation
Dilation refers to the expansion of blood vessels, allowing more blood to flow to the skin's surface, which helps to cool the body down. On the other hand, constriction refers to the narrowing of blood vessels, reducing blood flow to the skin's surface, which helps to conserve heat and warm the body. Therefore, dilation and constriction are mechanisms that the body uses to regulate body temperature by either cooling or warming it.Rate this question:
- 9.
What type of burn only affects the epidermis and upper regions of the dermis?
Correct Answer
2nd degree, second degree, 2 degreeExplanation
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:
- 10.
The papillary layer of the dermis consists of areolar connective tissue with collagen and elastic fibers.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The papillary layer of the dermis is composed of areolar connective tissue, which contains collagen and elastic fibers. This layer is located just below the epidermis and is responsible for providing support and nourishment to the overlying epidermis. Collagen fibers give strength and structure to the skin, while elastic fibers allow the skin to stretch and recoil. Therefore, the statement that the papillary layer of the dermis consists of areolar connective tissue with collagen and elastic fibers is true.Rate this question:
