3. assists in regulating temperature
4. supplements the body's intake of vitamin D by synthesizing this vitamin from UV light
epidermis - ANS outermost layer of skin
-consists of epithelial cells and melanocytes
dermis - ANS middle layer of skin
- thick layer composed mainly of connective tissue rich in collage and elastin
