Main purposes of skin:
- Protection: Keeps pathogens, chemicals out. Prevents loss of body fluids
- Houses nerve receptors: Detects temp, pain, touch pressure
- Secretes fluids: sweat and sebaceous glands maintain temp, and oil lubricates
- Temp regulation: sweat cools body release heat
Two layers of skin:
- Epidermis
Thin, outer layer.
- composed of stratified squamous epithelium (flat scale-like
cells arranged in overlapping layers)
- no blood supply
- Depends on deeper layer for nourishment
- deepest layer is basal layer;
cells grow and multiply, new cells push old cells toward surface; cells die.
-basal also contains melanocytes, produce the black pigment melanin;
responsible color skin, protects against uv ray damage
Two layers of skin:
- Dermis
Called corium
- fibrous connective tissue layer; between epidermis and
subcutaneous layer;
- “true skin
- has blood supply and collagen fibers
Hypodermis/ Subcutaneous layer
Not really a layer of skin, but assists.
- Fat cells called lipocytes, protect deeper tissue and insulation hot/cold
