Free Esthetician Practice Anatomy and Physiology Questions and Answers — Questions and Answers
Question 1: Which of the following are the two primary proteins that provide strength, flexibility, and elasticity to the skin and are predominantly found in the dermis?
- Keratin and Melanin
- Collagen and Elastin (Correct answer)
- Sebum and Sudor
- Fibroblasts and Adipose
Correct answer: Collagen and Elastin
Collagen and elastin are the two key structural proteins located in the dermis. Collagen provides the skin with its firmness and strength, while elastin allows the skin to stretch and return to its original shape, providing flexibility.
Question 2: A client is concerned about fine lines and the overall plumpness of their skin. An esthetician would recognize that the continuous renewal and health of the epidermis is due to cell division (mitosis) that primarily occurs in which layer?
- Stratum Corneum
- Stratum Granulosum
- Stratum Spinosum
- Stratum Germinativum (Basale) (Correct answer)
Correct answer: Stratum Germinativum (Basale)
The Stratum Germinativum, also known as the Stratum Basale, is the deepest layer of the epidermis. It is responsible for the regeneration of the epidermis through the process of mitosis, where new keratinocytes are formed and then pushed upwards.
Question 3: The skin's protective barrier, often referred to as the acid mantle, is a mixture of secretions from which two glands?
- Apocrine and Eccrine glands
- Sebaceous and Sudoriferous glands (Correct answer)
- Endocrine and Exocrine glands
- Mammary and Ceruminous glands
Correct answer: Sebaceous and Sudoriferous glands
The acid mantle is a crucial part of the skin's barrier function. It is composed of sebum, which is secreted by the sebaceous (oil) glands, and sweat, which is secreted by the sudoriferous (sweat) glands. This mixture creates a film with a slightly acidic pH that protects against pathogens.
Question 4: Which of the following is NOT a primary function of the skin?
- Sensation
- Heat Regulation
- Production of Vitamin C (Correct answer)
- Protection
Correct answer: Production of Vitamin C
The skin has six primary functions: Sensation, Heat Regulation, Absorption, Protection, Excretion, and Secretion. While the skin synthesizes Vitamin D with the help of sunlight, it does not produce Vitamin C.
Question 5: A client complains of oily skin. This is a result of overactive glands located in the dermis, which are responsible for secreting sebum. What are these glands called?
- Sudoriferous glands
- Apocrine glands
- Eccrine glands
- Sebaceous glands (Correct answer)
Correct answer: Sebaceous glands
Sebaceous glands are the oil-producing glands of the skin. They are connected to hair follicles and secrete sebum, an oily substance that lubricates the skin and hair. Overactivity of these glands leads to oily skin.
Question 6: During a facial massage, an esthetician applies pressure and strokes that stimulate nerve endings in the skin. Which type of nerve fibers are responsible for carrying sensations like touch, pressure, and temperature from the skin to the brain?
- Motor nerves
- Sensory nerves (Correct answer)
- Secretory nerves
- Autonomic nerves
Correct answer: Sensory nerves
Sensory nerves, also known as afferent nerves, are responsible for detecting stimuli from the environment, such as touch, pain, pressure, and temperature, and transmitting this information to the central nervous system for processing.
