EC Skin Anatomy and Physiology 2

Question 1

What is the primary function of the sebaceous gland in relation to the hair follicle?

Accepted Answer

Secreting sebum to lubricate the hair and skin

Answer

Producing melanin for hair color

Answer

Anchoring the hair to the follicle wall

Answer

Supplying blood to the dermal papilla

Question 2

The Fitzpatrick skin type classification system is used in electrolysis practice primarily to:

Accepted Answer

Assess skin's sensitivity to UV light and guide treatment parameters

Answer

Determine the client's age and hormone levels

Answer

Measure the depth of the hair follicle

Answer

Classify the type of hair growth disorder

Question 3

Which skin condition would be considered a contraindication for performing electrolysis in an affected area?

Accepted Answer

Active acne or inflamed skin lesions

Answer

Dry skin

Answer

Hyperpigmentation from sun exposure

Answer

Mild seborrheic dermatitis on the scalp

Question 4

What is the arrector pili muscle's role relevant to electrolysis treatment?

Accepted Answer

It is a smooth muscle that causes the hair to stand erect and can distort follicle angle

Answer

It controls blood flow to the dermal papilla

Answer

It produces the sebum that protects the follicle

Answer

It forms the inner root sheath around the hair

Question 5

The hypodermis (subcutaneous layer) is primarily composed of:

Accepted Answer

Adipose (fat) tissue and loose connective tissue

Answer

Dense irregular connective tissue

Answer

Stratified squamous epithelium

Answer

Smooth muscle fibers

Question 6

Which type of skin receptor detects pain and heat during an electrolysis procedure?

Accepted Answer

Free nerve endings (nociceptors)

Answer

Meissner's corpuscles

Answer

Pacinian corpuscles

Answer

Ruffini endings

Question 7

Skin with higher density of melanin (darker Fitzpatrick types) requires adjusted electrolysis technique primarily because:

Accepted Answer

Higher melanin content increases the risk of post-inflammatory hyperpigmentation if settings are too aggressive

Answer

Darker skin has deeper follicles that require longer probes

Answer

Melanin conducts electrical current more efficiently

Answer

Darker skin types have a thicker stratum corneum that blocks probe insertion
