Structure and Function Consists of 2 layers

Epidermis (outer) Dermis (inner)

Epidermis Composed of several

thin layers of epithelial tissues

No blood vessels or nerves

Provides protective covering to body

Contains melanocytes in deepest layer; produce melanin, gives skin color and protects against sunlight

Dermis a.k.a. corium thick layer of tissue contains various

structures blood vessels nerves hair follicles

sebaceous (oil) glands

sudoriferous (sweat) glands

Subcutaneous layer Layer of tissue below

the dermis Composed of adipose

tissue Function: connects

dermis to muscles and organs beneath it




Objective 4-2

Name the accessory structures of the integumentary system. Date: Lecture Outline

Figures, Tables, and Features



Content Text page

PPt slide

Accessory organs Hair and hair follicles

Composed of hard protein keratin

Color determined by pigment melanin

Nails Composed of keratin Provide protection to tip

of fingers and toes Composed of free edge,

nail plate, lunula, and cuticle

Sebaceous (oil) glands Associated with hair

follicles Secrete oil that provides

lubrication to skin Sudoriferous (sweat) glands

Most numerous in palms, soles of feet, forehead, and armpits

Secrete watery fluid, helps cool the body
