One of the largest dermal exocrine glands located in the axilla and genital areas. It secrets sweat that, in action with bacteria, is responsible for human body odor.

3

Basal layer

Deepest region of the epidermis; it gives rise to all the epidermis cells.

4

Collagen

5

Cuticle

Band of epidermis at the base and sides of the nail plate.

6

Dermis

The middle layer of the skin.

8

Epidermis

Outermost layer of the skin.

9

Epithelium

Layer of the skin cells forming the outer and inner surfaces of the body.

10

Hair follicle

Sac within which the hair grows.

11

Integumentary System

The skin and its accessory structures such as hair and nails.

13

Lunula

The half-moon-shaped, whitish area at the base of a nail.

14

Melanin

Skin pigment. It is formed by melanocytes in the epidermis. Eumelanin is brown-black pigment, while pheomelanin is red-yellow.
