Esthetician Practice Exam FREE Esthetician Practice Anatomy and Physiology Questions and Answers 2 — Questions and Answers
Question 1: Which layer of the skin contains blood vessels, nerve endings, and collagen fibers?
- Epidermis
- Dermis (Correct answer)
- Hypodermis
- Stratum corneum
Correct answer: Dermis
The dermis is the middle layer of skin that houses blood vessels, nerve endings, collagen, and elastin fibers.
Question 2: What is the primary function of melanocytes in the skin?
- Produce keratin for skin strength
- Produce melanin for UV protection (Correct answer)
- Regulate body temperature
- Facilitate wound healing
Correct answer: Produce melanin for UV protection
Melanocytes produce melanin, which absorbs ultraviolet radiation and protects deeper skin layers from sun damage.
Question 3: Which muscle type is responsible for producing goosebumps on the skin?
- Skeletal muscle
- Cardiac muscle
- Arrector pili muscle (Correct answer)
- Orbicularis oculi muscle
Correct answer: Arrector pili muscle
The arrector pili muscles are tiny smooth muscles attached to hair follicles that contract to cause goosebumps.
Question 4: What structure in the skin is primarily responsible for producing sweat to regulate body temperature?
- Sebaceous glands
- Eccrine glands (Correct answer)
- Apocrine glands
- Ceruminous glands
Correct answer: Eccrine glands
Eccrine glands are distributed across most of the body and produce watery sweat to cool the body through evaporation.
Question 5: Which type of tissue makes up the subcutaneous layer beneath the dermis?
- Epithelial tissue
- Muscle tissue
- Adipose tissue (Correct answer)
- Cartilage tissue
Correct answer: Adipose tissue
The subcutaneous layer, or hypodermis, is primarily composed of adipose (fat) tissue that insulates the body and cushions deeper structures.
Question 6: What is the function of the stratum lucidum in the epidermis?
- Produces new skin cells through mitosis
- Provides a clear, transitional barrier found mainly on palms and soles (Correct answer)
- Contains melanocytes for pigmentation
- Sheds dead skin cells from the surface
Correct answer: Provides a clear, transitional barrier found mainly on palms and soles
The stratum lucidum is a thin, translucent layer found only in thick skin areas like the palms and soles, providing an extra barrier.
