Questions with Answers & EXPERT RATIONALE
SECTION 1: SKIN ANATOMY & PHYSIOLOGY
1. What is the outermost layer of the skin?
A) Dermis
B) Hypodermis
C) Stratum granulosum
D) Stratum spinosum
E) Epidermis
Correct Answer: E) Epidermis
EXPERT RATIONALE: The epidermis is the outermost layer of the skin. It acts as
the first line of defense against environmental factors. It contains no blood vessels
and is made up of five sub-layers, with the stratum corneum being the most
superficial.
,2. Which layer of the epidermis contains melanocytes?
A) Stratum corneum
B) Stratum lucidum
C) Stratum granulosum
D) Stratum spinosum
E) Stratum basale
Correct Answer: E) Stratum basale
EXPERT RATIONALE: Melanocytes, the cells responsible for producing melanin
(the pigment that gives skin its color), are found in the stratum basale, the deepest
layer of the epidermis. Melanin also helps protect the skin from UV radiation.
3. What is the main protein that makes up the epidermis?
A) Collagen
B) Elastin
C) Actin
D) Keratin
E) Fibrin
Correct Answer: D) Keratin
EXPERT RATIONALE: Keratin is a fibrous structural protein that makes up the
majority of the epidermis, hair, and nails. It provides strength and waterproofing to
the skin's surface and is produced by keratinocytes.
4. Which layer of the skin contains collagen and elastin fibers?
A) Epidermis
,B) Stratum corneum
C) Dermis
D) Stratum basale
E) Hypodermis
Correct Answer: C) Dermis
EXPERT RATIONALE: The dermis is the second layer of skin, located beneath
the epidermis. It contains collagen for structure and strength, and elastin for
elasticity. It also houses hair follicles, sweat glands, sebaceous glands, nerve
endings, and blood vessels.
5. What is the function of sebaceous glands?
A) Regulate body temperature
B) Produce sweat
C) Produce sebum to lubricate skin and hair
D) Produce melanin
E) Filter toxins from the skin
Correct Answer: C) Produce sebum to lubricate skin and hair
EXPERT RATIONALE: Sebaceous glands are oil-producing glands found in the
dermis. They secrete sebum, which lubricates and waterproofs the skin and hair,
preventing dryness and protecting against bacteria.
6. The hypodermis is primarily composed of which tissue?
A) Muscle tissue
B) Epithelial tissue
C) Connective tissue only
, D) Adipose (fat) tissue
E) Nervous tissue
Correct Answer: D) Adipose (fat) tissue
EXPERT RATIONALE: The hypodermis, also called the subcutaneous layer, is
primarily made up of adipose (fat) tissue. It acts as insulation, energy storage, and a
cushion for the body. It connects the skin to underlying muscles and bones.
7. Which cells in the epidermis are responsible for immune defense?
A) Melanocytes
B) Keratinocytes
C) Langerhans cells
D) Fibroblasts
E) Merkel cells
Correct Answer: C) Langerhans cells
EXPERT RATIONALE: Langerhans cells are dendritic immune cells found
primarily in the stratum spinosum of the epidermis. They detect and respond to
foreign invaders and are a key part of the skin's immune defense system.
8. What is the stratum corneum composed of?
A) Living keratinocytes
B) Melanocytes and Langerhans cells
C) Dead, flattened keratinized cells
D) Collagen fibers
E) Sebaceous secretions
Correct Answer: C) Dead, flattened keratinized cells
