Question 1: What is the outermost layer of the skin?
A. Dermis B. Hypodermis C. Epidermis D. Subcutaneous layer E. Stratum basale

CORRECT ANSWER: C. Epidermis RATIONALE: The epidermis is the
outermost layer of the skin. It serves as the body's first line of defense against
environmental factors, pathogens, and water loss.



Question 2: Which layer of the epidermis is responsible for producing new skin
cells?

A. Stratum corneum B. Stratum lucidum C. Stratum granulosum D. Stratum basale E.
Stratum spinosum

CORRECT ANSWER: D. Stratum basale RATIONALE: The stratum basale,
also called the basal layer, is the deepest layer of the epidermis where mitosis (cell
division) occurs to produce new keratinocytes that migrate upward.


Question 3: How many layers does the epidermis consist of?

A. Three B. Four C. Five D. Six E. Seven

CORRECT ANSWER: C. Five RATIONALE: The epidermis consists of five
layers: stratum corneum, stratum lucidum (only in thick skin), stratum granulosum,
stratum spinosum, and stratum basale.



Question 4: Which skin layer contains collagen and elastin fibers?

A. Epidermis B. Stratum corneum C. Dermis D. Hypodermis E. Stratum granulosum

, CORRECT ANSWER: C. Dermis RATIONALE: The dermis is the second
layer of the skin and contains collagen and elastin fibers, which provide skin with its
strength, elasticity, and structure.


Question 5: What is the primary function of melanocytes?

A. Producing keratin B. Providing immunity C. Producing melanin for skin pigmentation
D. Regulating oil production E. Sensing touch and pressure

CORRECT ANSWER: C. Producing melanin for skin pigmentation
RATIONALE: Melanocytes are specialized cells located in the stratum basale that
produce melanin, the pigment responsible for skin, hair, and eye color, and that provides
some UV protection.



Question 6: The stratum corneum is composed mainly of which type of cells?
A. Living keratinocytes B. Melanocytes C. Dead, flattened keratinized cells D.
Langerhans cells E. Fibroblasts

CORRECT ANSWER: C. Dead, flattened keratinized cells RATIONALE:
The stratum corneum is the outermost epidermal layer, made up of dead, flattened,
keratinized cells (corneocytes) that form a protective barrier against the environment.



Question 7: Which skin type is characterized by enlarged pores, shine, and
frequent breakouts?

A. Dry skin B. Normal skin C. Sensitive skin D. Oily skin E. Combination skin

CORRECT ANSWER: D. Oily skin RATIONALE: Oily skin (seborrhea) is
characterized by excess sebum production, enlarged pores, a shiny appearance, and a
tendency toward comedones and acne breakouts.



Question 8: What is the acid mantle?

A. A chemical peel applied during facials B. A protective film of sebum and sweat on the
skin's surface C. A layer of the epidermis D. A type of moisturizer E. An enzyme found in
the dermis

, CORRECT ANSWER: B. A protective film of sebum and sweat on the skin's
surface RATIONALE: The acid mantle is a thin, slightly acidic film on the surface
of the skin formed by sebum and sweat. It has a pH of 4.5–5.5 and helps protect the
skin from bacteria, viruses, and other contaminants.


Question 9: Which glands are responsible for producing sweat?

A. Sebaceous glands B. Sudoriferous glands C. Ceruminous glands D. Mammary
glands E. Lacrimal glands

CORRECT ANSWER: B. Sudoriferous glands RATIONALE: Sudoriferous
glands, also known as sweat glands, are responsible for producing sweat, which helps
regulate body temperature and eliminate waste products.



Question 10: What is the normal pH range of healthy skin?
A. 6.5–7.5 B. 3.0–4.0 C. 4.5–5.5 D. 7.0–8.0 E. 2.0–3.0

CORRECT ANSWER: C. 4.5–5.5 RATIONALE: Healthy skin is slightly acidic
with a pH of 4.5–5.5. This acidic environment, maintained by the acid mantle, helps
protect against microbial growth and environmental damage.



Question 11: Which nerve fibers in the skin respond to pain?
A. Ruffini endings B. Meissner's corpuscles C. Pacinian corpuscles D. Nociceptors E.
Merkel's discs

CORRECT ANSWER: D. Nociceptors RATIONALE: Nociceptors are sensory
receptors in the skin that detect potentially damaging stimuli such as extreme heat, cold,
or pressure, and send pain signals to the brain.



Question 12: The hypodermis is primarily composed of which tissue?

A. Muscle tissue B. Epithelial tissue C. Adipose (fat) tissue D. Nerve tissue E.
Connective tissue only

CORRECT ANSWER: C. Adipose (fat) tissue RATIONALE: The hypodermis
(subcutaneous layer) lies beneath the dermis and is primarily composed of adipose (fat)
tissue, which provides insulation, cushioning, and energy storage.

, Question 13: What is desquamation?

A. The production of new skin cells B. The shedding of dead skin cells from the surface
C. The formation of scar tissue D. The process of melanin synthesis E. Excessive oil
production

CORRECT ANSWER: B. The shedding of dead skin cells from the surface
RATIONALE: Desquamation is the natural process of shedding dead skin cells
(corneocytes) from the stratum corneum. This process occurs approximately every 28
days in younger adults.


Question 14: Which skin appendage produces sebum?

A. Sudoriferous glands B. Hair follicles C. Sebaceous glands D. Eccrine glands E.
Apocrine glands

CORRECT ANSWER: C. Sebaceous glands RATIONALE: Sebaceous
glands are oil-producing glands attached to hair follicles that secrete sebum, a waxy
substance that lubricates and waterproofs the skin and hair.



Question 15: What is the term for the process by which skin cells move from the
basal layer to the surface?

A. Mitosis B. Keratinization C. Desquamation D. Melanogenesis E. Fibroplasia

CORRECT ANSWER: B. Keratinization RATIONALE: Keratinization is the
process by which newly produced cells in the stratum basale gradually fill with the
protein keratin and move upward through the epidermal layers, eventually becoming the
dead, flattened cells of the stratum corneum.



Question 16: Which cells in the epidermis are part of the immune system?

A. Keratinocytes B. Melanocytes C. Langerhans cells D. Fibroblasts E. Merkel cells

CORRECT ANSWER: C. Langerhans cells RATIONALE: Langerhans cells
are dendritic immune cells found primarily in the stratum spinosum. They help detect
foreign substances and play a key role in the skin's immune response.
