Learning
1. Which three parts of the body comprise the integumentary system?
A) Skin, hair, and nails
B) Skin, muscles, and bones
C) Hair, nails, and glands
D) Epidermis, dermis, and hypodermis
Correct Answer: Skin, hair, and nails
Rationale: The integumentary system is comprised of skin, hair, and nails.
The skin includes the epidermis, dermis, and hypodermis as its layers, but
these are not separate components of the system .
2. The layers of the skin from superficial to deep are:
A) Hypodermis, dermis, epidermis
B) Epidermis, dermis, hypodermis
C) Dermis, epidermis, hypodermis
D) Epidermis, hypodermis, dermis
Correct Answer: Epidermis, dermis, hypodermis
Rationale: The skin layers from superficial to deep are the epidermis
(outermost), dermis (middle), and hypodermis (deepest subcutaneous layer).
This order is fundamental to understanding skin structure and is regularly
tested .
3. Which of the following is NOT a function of the integumentary system?
A) Production of vitamin D
,B) Protection from pathogens
C) Digestion of food
D) Containment of sense organs
Correct Answer: Digestion of food
Rationale: The integumentary system provides protection, synthesizes
vitamin D, and contains sensory organs. Digestion is a function of the
digestive system, making it the incorrect option for this question .
4. The epidermis is composed of which type of epithelium?
A) Stratified cuboidal epithelium
B) Simple squamous epithelium
C) Stratified squamous epithelium
D) Transitional epithelium
Correct Answer: Stratified squamous epithelium
Rationale: The epidermis is made up of stratified squamous epithelium, not
stratified cuboidal epithelium. This layered, flattened cell arrangement
provides a durable, protective barrier for the body surface .
5. The four layers of the epidermis from superficial to deep are:
A) Stratum corneum, stratum granulosum, stratum spinosum, stratum basale
B) Stratum basale, stratum spinosum, stratum granulosum, stratum corneum
C) Stratum corneum, stratum spinosum, stratum granulosum, stratum basale
D) Stratum spinosum, stratum granulosum, stratum corneum, stratum basale
, Correct Answer: Stratum corneum, stratum granulosum, stratum spinosum,
stratum basale
Rationale: From the surface inward, the epidermal layers are stratum
corneum, stratum granulosum, stratum spinosum, and stratum basale. This
order reflects keratinocyte maturation as cells move toward the surface .
6. Cells of the stratum basale have which characteristic?
A) Low rate of cell division
B) High rate of cell division
C) No nucleus
D) No metabolic activity
Correct Answer: High rate of cell division
Rationale: The stratum basale is the deepest epidermal layer where new
cells are produced through mitosis. These cells divide rapidly to replace cells
shed from the surface .
7. The basis for each person's distinct fingerprint pattern is formed by:
A) Melanocytes
B) Keratinocytes
C) Epidermal ridges
D) Sebaceous glands
Correct Answer: Epidermal ridges
