the skin provides protection against abrasion and ultraviolet light; it also prevents the entry of microorganisms and dehydration by reducing water loss from the body

it has sensory receptors that can detect heat, cold, touch, pressure, and pain.

when exposed to ultraviolet light, the skin produces a molecule that can be transformed into vit D.

body temperature is regulated by controlling blood flow through the skin and the activity of the sweat glands

small amounts of waste products are lost through the skin and in gland secretions.

(upon the dermis) is a layer of epithelial tissue that rests on the dermis. Also Prevent water loss and resists abrasion

-(skin) is a layer of dense connective tissue.

-10 to 20 times thicker that the epidermis.

-responsible for the most of the structural strength of the skin.

• - Composes most of the epidermis

• - Produces keratin that protects the skin & the underlying tissues

• - Tactile cells

• - Sensory receptors (touch)

• - Usually associated with a disc-like sensory

nerve ending to form the Merkel disc

• - the pigment “melanin” which protects the skin from UVR in sunlight

• - responsible for skin pigmentation or color (brown-black pigment)

• - Found chiefly in the stratum basale
