AAM Anatomy & Physiology of the Skin

Question 1

Which of the following correctly lists the three primary layers of the skin from outermost to innermost?

Accepted Answer

Epidermis, dermis, hypodermis

Answer

The skin is composed of three layers: the epidermis (outermost), dermis (middle), and hypodermis/subcutaneous layer (deepest).

Question 2

In which skin layer should micropigmentation pigment ideally be deposited to ensure long-lasting results?

Accepted Answer

Papillary dermis

Answer

Pigment placed in the papillary dermis is stable and long-lasting because this layer does not shed like the epidermis, yet is not so deep that pigment migrates or blurs.

Question 3

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

Accepted Answer

Melanocytes

Answer

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

Question 4

Which layer of the epidermis is the deepest and is the site of active mitotic cell division?

Accepted Answer

Stratum basale

Answer

The stratum basale (basal layer) is the deepest epidermal layer where stem cells undergo mitosis to generate new keratinocytes that migrate upward.

Question 5

Approximately how long does it take for epidermal cells to migrate from the stratum basale to the surface and be shed?

Accepted Answer

28 to 45 days

Answer

The full epidermal cell turnover cycle is approximately 28 to 45 days, which is why pigment placed too superficially fades quickly as cells shed.
