SECTION 1: SKIN ANATOMY & PHYSIOLOGY
1. What is the outermost layer of the skin?
A) Dermis
B) Hypodermis
C) Stratum granulosum
D) Subcutaneous layer
E) Epidermis
Correct Answer: E) Epidermis
EXPERT RATIONALE: The epidermis is the outermost layer of the skin. It acts as
the first barrier against environmental damage, pathogens, and water loss. It
contains no blood vessels and is composed of five sublayers.
,2. Which layer of the epidermis contains melanocytes?
A) Stratum corneum
B) Stratum spinosum
C) Stratum granulosum
D) Stratum lucidum
E) Stratum basale
Correct Answer: E) Stratum basale
EXPERT RATIONALE: The stratum basale (basal layer) is the deepest layer of the
epidermis and is where melanocytes are found. These cells produce melanin, the
pigment responsible for skin color and UV protection.
3. What is the function of sebaceous glands?
A) Regulate body temperature through sweat
B) Produce keratin for skin protection
C) Absorb nutrients into the bloodstream
D) Produce collagen and elastin fibers
E) Secrete sebum to lubricate the skin and hair
Correct Answer: E) Secrete sebum to lubricate the skin and hair
EXPERT RATIONALE: Sebaceous glands are oil-producing glands attached to
hair follicles. They secrete sebum, which lubricates and waterproofs the skin and
hair, and also has mild antibacterial properties.
4. Which skin layer contains collagen and elastin fibers?
A) Epidermis
B) Stratum corneum
,C) Stratum basale
D) Dermis
E) Hypodermis
Correct Answer: D) Dermis
EXPERT RATIONALE: The dermis lies beneath the epidermis and contains
collagen and elastin fibers, which provide the skin with strength, structure, and
elasticity. It also houses blood vessels, nerves, and glands.
5. How many layers does the epidermis contain?
A) Three
B) Two
C) Seven
D) Six
E) Five
Correct Answer: E) Five
EXPERT RATIONALE: The epidermis is composed of five layers: stratum
corneum, stratum lucidum (only in thick skin), stratum granulosum, stratum
spinosum, and stratum basale. Each layer plays a distinct role in skin health and
protection.
6. Which cells in the skin are responsible for immune defense?
A) Keratinocytes
B) Melanocytes
C) Fibroblasts
D) Langerhans cells
, E) Merkel cells
Correct Answer: D) Langerhans cells
EXPERT RATIONALE: Langerhans cells are specialized immune cells found in
the epidermis, primarily in the stratum spinosum. They detect and respond to
pathogens and allergens, playing a critical role in the skin's immune defense.
7. The process by which skin cells move from the basal layer to the surface is
called:
A) Melanogenesis
B) Keratinization only
C) Desquamation
D) Mitosis exclusively
E) Cell turnover (keratinization)
Correct Answer: E) Cell turnover (keratinization)
EXPERT RATIONALE: Cell turnover, also known as keratinization, is the process
by which new cells formed in the stratum basale migrate upward, become filled
with keratin, and eventually shed from the surface. This cycle takes approximately
28–45 days.
8. What type of tissue makes up the hypodermis?
A) Muscle tissue
B) Epithelial tissue
C) Nerve tissue
D) Connective tissue only
E) Adipose (fatty) tissue
Correct Answer: E) Adipose (fatty) tissue
