Question 1

What are the three main layers of the skin listed from outermost to innermost?

Accepted Answer

Epidermis, dermis, hypodermis

Answer

The skin consists of three layers: the epidermis (outermost), the dermis (middle), and the hypodermis or subcutaneous layer (innermost).

Question 2

The deepest, most active layer of the epidermis responsible for cell renewal is called the:

Accepted Answer

Stratum basale

Answer

The stratum basale (basal layer) is the deepest epidermal layer containing stem cells that continuously divide to replenish the epidermis.

Question 3

Which cells in the epidermis are responsible for producing the pigment melanin?

Accepted Answer

Melanocytes

Answer

Melanocytes are specialized cells located in the stratum basale that produce melanin, the pigment responsible for skin and hair color.

Question 4

In which skin layer are the hair follicle bulbs primarily located?

Accepted Answer

Dermis

Answer

Hair follicle bulbs are located in the dermis (and may extend into the hypodermis for terminal hairs), making the dermis the target layer for electrolysis.

Question 5

What is the outermost sublayer of the epidermis composed of?

Accepted Answer

Dead, flattened, keratinized cells
