Anatomy and Physiology Study Set 1

In healthy skin, the production of epidermal cells is closely balanced with the loss of skin cells.

Blood carrying excess oxygen results in cyanosis.

The outermost layer of the epidermis is stratum basale and the innermost layer is stratum corneum.

On its superficial aspect, the epidermis has ridges called papillae that project upward toward the surface of the skin.

Carcinomas appear most often in the skin of the neck, face, and scalp.

Three physiological factors that can affect the color of skin are the volume of blood in dermal vessels, the amount of oxygen carried by the blood, and presence of carotene in the subcutaneous layer.

The secretion of the sebaceous glands is called sebum.

Hair color is determined by the amount of keratin protein produced during keratinization.

When the body temperature rises abovenormal, dermal blood vessels are likely to constrict.

The nerve fibers scattered throughout the dermis are associated with what structures?

Which of the following does NOT describe the skin?

What is happening to epidermal cells as they are pushed from the deeper part of the epidermis toward the surface?

Sweat glands and sebaceous glands are located in the __________.

Where are blood vessels located that supply the skin?

Cutaneous carcinomas develop from what type of skin cell?

Prolonged bedrest can result in the development of __________ in areas of skin overlying bony projections.

What is the function of melanocytes?

Epidermal cells are supplied with nutrients from blood vessels located in what layer?

What is the most common cause of cutaneous melanoma?

Injections called __________ are those that are administered into the skin.
