subcutaneous tissue
supports, nourishes, insulates and cusions the skin
What does hair do?
provides sensation and some protection for the head
What do nails do?
Protects ends of fingers and toes.
What are nails composed of?
They are horny cell structures of the epidemis and composed of hard keratin.
sebaceous glands
lubricates the hair and skin
sweat (sudoriferous) glands
secretes sweat or perspiration
Protection function of the skin (1)
serves as a protective membrane against invasion by bacteria
Protection function of the skin (2)
serves to inhibit loss of water and eletrolytes
Protection function of the skin (3)
helps to produce the body's supply of vitamin D
Regulation function of the skin
serves to raise and lower body temperature as necessary
Sensation function of the skin (1)
skin contains millions of microscopic nerve endings that act as sensory receptors for pain, touch, heat, cold and pressure
Sensation function of the skin (2)
When stimuation occurs, nerve impluses are sent to the cerebral cortex of the brain
Secretion function of the skin (1)
skin contains millions of sweat glands, which secrete perspiration or sweat
Secretion function of the skin (2)
skin contains sebaceous glands, which secrete oil for lubrication
sebaceous glands
produce sebum, which acts to protect the body from dehydration
