Document Summary
Composed of stratified squamous epithelium (several layers of flat epithelial cells) Keratinocytes contributes to skin thickening and toughening. Lies below the epidermis and is attached to underlying subcutaneous tissue (sc tissue is made up primarily of connective tissue with many adipocytes fat cells) Stabilizes position of skin relative to underlying tissues. Due to the location of the vessels, we have terms such as: Hair grows out of a follicle from root to shaft. Follicles are found within the sc tissue and dermis. Hairs provide sensory input, protect nares and ears from foreign material, protect the scalp from uv damage. Secrete sebum (oily liquid) onto skin and along hair shafts. Function is to lubricate skin and provide antibacterial protection. Two kinds: apocrine sweat glands (found in armpits, groin, nipples thick secretion; also in outer ears cerumen production, and nipples - milk) merocrine sweat glands (cover the body, thin watery secretions thermoregulation and excretion)
