what are the two layers of the skin?

Back 3

inner layer= dermis outer layer= epidermis

Front 4

what is under the dermis but not a part of the skin?

Back 4

subcutaneous layer

Front 5

What does the epidermis consist of? what type of tissue is it?

Back 5

consists of epithelial cells, melanocytes, and keratinocytes, tissue type is epithelial tissue

Front 6

what is the function of the epidermis?

Back 6

covers the body and lines the body cavities

Front 7

What are melanocytes responsible for?

Back 7

skin color, they produce melanin, more melanin = darker skin

Front 8

what are keratinocytes responsible for?

Back 8

producing keratin, makes epithelial cells tough, waterproof, and resistant to bacteria

Front 9

what does the basal cell layer of epithelium do?
