INTEGUMENTARY SYSTEM
includes skin, glands, hair, and nails. The skin provides protective covering for the body and aids in the identification of heat, cold, pain, and touch. The glands produce sweat to help cool the body and oil to lubricate the skin. Nails provide protection for the tips of the fingers and toes.
- Skin===Protection
- Hair==Temp. control (Thermoregulation)
- Nails---Sensory
- Glands==lubrication
-
SKINS AND GLANDS
Largest organ of the body and has two layers:
- 1) Epidermis: outermost layer of the skin
- 2) Dermis: The inner or middle layer of the skin
- 3) Subcutaneous- Closely attached to the dermis.
-
EPIDERMIS
Outer most layer. Covered with flat horny cells. Another epidermal layer contains melanin, the substance that gives skin color. The last Epidermal layer called Basil layer, produces new cells to replace those that are being shed
-
MELANOCYTES
Produces melanin it's in the lower layer of the epidermis we all have melanin, the amount differs.
-
DERMIS/"TRUE SKIN"
Contains blood vessels, sensory nerve endings, oils and sweat glands and hair follociles. Sebaceous glands secrete Sebum or oil into hair follicles, sweat glands also called Sudoriferous glands emerge through pores to the surface of the skin.
SEBUM==Seb/o
has all the structure needed to keep skin alive.
-
SUBCUTANEOUS TISSUE
Not a layer of skin, but closely associated with the dermal layer of the skin. It's made of adipose, fatty tissue and connective tissue. provides insulation and protection for deeper body structures.
-
-
HAIR AND NAILS
Meshwork of cells that contain the protein Keratin. It originates from the Hair Follicles which are located in the dermis of the skin. The hair Root is embedded in the hair follicle. The arrector pili muscle provides support for hair follicles. The Shaft is the visible portion of the hair. Hair shaft is actually dead tissue and does not have nerve ending
