Esthetician Practice Anatomy and Physiology Questions and Answers — Questions and Answers
Question 1: A client is concerned about loss of skin firmness and the recent appearance of fine lines. An esthetician would explain that these changes are likely due to a decrease in the production of which two proteins found in the dermis?
- Keratin and Melanin
- Collagen and Elastin (Correct answer)
- Sebum and Sudor
- Hyaluronic Acid and Glycosaminoglycans
Correct answer: Collagen and Elastin
Collagen and elastin are the two primary structural proteins located in the dermis, the middle layer of the skin. Collagen provides strength and firmness, while elastin supplies elasticity and rebound, allowing the skin to return to its original shape. A decline in the production of these proteins with age leads to wrinkles and sagging.
Question 2: Cellular division, or mitosis, which is responsible for the regeneration of the epidermis, occurs primarily in which layer of the skin?
- 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 contains basal cells that constantly undergo mitosis to produce new keratinocytes, which then migrate up through the other layers of the epidermis.
Question 3: During a facial massage, an esthetician applies pressure and performs movements over the cheeks, forehead, and jawline. Sensation from these areas is primarily carried to the brain by which cranial nerve?
- Facial Nerve (VII)
- Trigeminal Nerve (V) (Correct answer)
- Vagus Nerve (X)
- Accessory Nerve (XI)
Correct answer: Trigeminal Nerve (V)
The Trigeminal Nerve (Cranial Nerve V) is the largest cranial nerve and is the principal sensory nerve of the face. It has three branches (ophthalmic, maxillary, and mandibular) that are responsible for transmitting sensations of touch, pain, and temperature from the face to the brain.
Question 4: Which of the following are the two primary types of sudoriferous glands, which have distinct functions related to cooling the body and producing odor?
- Sebaceous and Ceruminous
- Apocrine and Eccrine (Correct answer)
- Holocrine and Merocrine
- Endocrine and Exocrine
Correct answer: Apocrine and Eccrine
The sudoriferous (sweat) glands are divided into two main types: eccrine and apocrine. Eccrine glands are found all over the body and their primary function is thermoregulation by secreting water and electrolytes. Apocrine glands are located in areas like the axillae and groin, and their secretions, when broken down by bacteria, are responsible for body odor.
Question 5: A client is scheduled for a manual lymphatic drainage (MLD) massage to reduce puffiness. Which of the following conditions reported on their health history form would be an absolute contraindication for this service?
- First Trimester of Pregnancy
- Mild Seasonal Allergies
- Acute Infection with Fever (Correct answer)
- Well-controlled Hypothyroidism
Correct answer: Acute Infection with Fever
An acute infection with fever is an absolute contraindication for manual lymphatic drainage. MLD stimulates the lymphatic system, and performing it during an active infection can potentially spread the pathogens throughout the body, worsening the condition.
Question 6: Which layer of the epidermis is the most superficial and is composed of 20-30 layers of dead, flattened keratinocytes that provide a protective barrier?
- Stratum Lucidum
- Stratum Basale
- Stratum Spinosum
- Stratum Corneum (Correct answer)
Correct answer: Stratum Corneum
The Stratum Corneum is the outermost layer of the epidermis. It consists of dead, anucleated cells (corneocytes) filled with keratin. This layer functions as the primary barrier between the body and the environment, protecting against pathogens, water loss, and physical trauma.
