Section 1: Skin Anatomy and Physiology
Q1: The layer of skin where hair follicles originate is the:
A. Epidermis
B. Dermis [CORRECT]
C. Subcutaneous layer
D. Stratum corneum
Correct Answer: B
Rationale: Hair follicles are rooted in the dermis, the thick layer of living tissue below the
epidermis. The epidermis is the outer protective layer. The subcutaneous layer is fatty tissue
below the dermis.
Q2: Which of the following is responsible for the sensation of touch and pain in the skin?
A. Melanocytes
B. Sensory nerve endings [CORRECT]
C. Sebaceous glands
D. Arrector pili muscles
Correct Answer: B
Rationale: Sensory nerve endings detect stimuli such as touch, pain, and temperature.
Melanocytes produce pigment. Sebaceous glands produce oil. Arrector pili muscles cause
goosebumps.

Q3: The "growth zone" of the skin, where new skin cells are generated, is the:
A. Stratum corneum
B. Stratum lucidum
C. Stratum basale (germinativum) [CORRECT]
D. Stratum granulosum
Correct Answer: C
Rationale: The stratum basale is the deepest layer of the epidermis where mitosis (cell division)
occurs to produce new keratinocytes. The stratum corneum is the dead, outermost layer.
Q4: A client presents with thick, callused skin on the soles of their feet. Which layer of the
epidermis is most prominent in this area?
A. Stratum lucidum [CORRECT]
B. Stratum spinosum
C. Stratum granulosum
D. Stratum basale
Correct Answer: A
Rationale: The stratum lucidum is a thin, clear layer found only in thick skin (palms of hands and
soles of feet). It provides an extra layer of toughness.
Q5: The vascular supply to the skin is located primarily in the:
A. Epidermis
B. Dermis [CORRECT]
C. Stratum corneum
D. Hair shaft
,3
Correct Answer: B
Rationale: The dermis contains blood vessels (capillaries) that nourish the skin and help regulate
body temperature. The epidermis is avascular (has no blood supply).
Q6: Which skin type on the Fitzpatrick scale is most at risk for burning and least likely to tan?
A. Type I [CORRECT]
B. Type III
C. Type V
D. Type VI
Correct Answer: A
Rationale: Fitzpatrick Type I skin is very pale, always burns, and never tans. This skin type
requires the most caution with laser treatments to avoid thermal damage.
Q7: The protein that provides toughness and waterproofing to the skin and hair is:
A. Collagen
B. Elastin
C. Keratin [CORRECT]
D. Melanin
Correct Answer: C
Rationale: Keratin is a fibrous protein that makes up the structure of the epidermis, hair, and
nails. Collagen provides strength to the dermis, while elastin provides flexibility.
Q8: The small muscles attached to hair follicles that cause "goosebumps" are called:
A. Dermal papillae
B. Arrector pili [CORRECT]
C. Sudoriferous glands
, 4
D. Melanocytes
Correct Answer: B
Rationale: The arrector pili are smooth muscle fibers that contract in response to cold or fear,
pulling the hair follicle upright and raising the skin surface.
Q9: Which gland secretes sebum into the hair follicle?
A. Sudoriferous gland
B. Sebaceous gland [CORRECT]
C. Endocrine gland
D. Apocrine gland
Correct Answer: B
Rationale: Sebaceous glands are connected to hair follicles and secrete sebum (oil) to lubricate
the skin and hair. Sudoriferous glands produce sweat.
Q10: The hydrolipidic film on the skin's surface functions to:
A. Cool the body
B. Protect against bacteria and moisture loss [CORRECT]
C. Produce vitamin D
D. Create pigment
Correct Answer: B
Rationale: The hydrolipidic film (acid mantle) is an emulsion of water (sweat) and oil (sebum)
that acts as a barrier against pathogens and dehydration.
Q11: A client has a history of keloid formation. This indicates an abnormal healing response
involving excess:
