Functions of the Integumentary System

Protects from injury, infection, dehydration, regulates body temperature, provides sensory information, produces Vitamin D, and prevents water loss.

Epidermis

Outermost layer of skin, contains no blood vessels, and is thickest on soles of feet.

Dermis

Middle layer of skin made of dense connective tissue, rich in collagen fibers, and contains hair follicles, sweat glands, sebaceous glands, blood vessels, and nerve endings.

Hypodermis

Deepest layer of skin that anchors skin to underlying organs and contains adipose tissue for insulation and cushioning.

Melanin

Pigment produced by melanocytes that determines skin color.

Sebaceous Glands

Oil glands that secrete sebum to keep skin lubricated and waterproof; most numerous on face and scalp.

Sudoriferous Glands

Sweat glands that include eccrine and apocrine glands, involved in temperature regulation.

Ceruminous Glands

Glands that produce cerumen, or earwax.
