largest

Describe the epidermis

Back 4

Most superficial layer of the skin; it does not contain any blood vessels; provides skin with the waterproofing property and also contains melanin (a black pigment), which protects the skin from the suns harmful rays

Front 5

Describe the dermis

Back 5

Located directly deep to the epidermis; Contains blood and lymph vessels, nerve fibres and the accessory organs of the skin; Responsible to provide protection (i.e. cells that engulf foreign particles – hisitocytes), recognize sensory impulses (i.e. perceive pain, temp, touch) through the nerves and provides materials to heal (i.e. fibroblasts and collagen); Contains mast cells present that respond to injury by producing histamine (decrease itching) and heparin (anticoagulant)

Front 6

Describe the Subcutaneous layer

Back 6

Deepest layer, composed of connective tissue, contains a large amount of fat

Front 7

What are the 10 functions of the skin?

Back 7

1. aids in the immunologic system (histiocytes on dermis); 2. Water proofs the body (epidermis); 3. Prevents loss of fluid; 4. Provides colouration (melanin in epidermis); 5. Regulate body temperature (sweat glands); 6. Lubricates skin which discourages bacterial growth (sebaceous glands); 7. Provides a site for vitamin D synthesis – exposure to sunlight (controls calcium and phosphorus levels in the body). 8. Controls heat loss (hair). 9. Sense reception (hair). 10. Protection of phalanx (nail)

Front 8

What does the dermis contain?
