Identify the functions of Integumentary System Terms

Melanin

Location: Deep in the skin (only in Stratum Basale layer) Melanin is a pigment produced by Melanocytes; Melanin protects cells from UV rays; Melanin is deposited into keratinocytes

Keratin

Location: nearly all cells in the epidermis Keratin is produced by keratinocytes by filling themselves up with Keratin then no longer function and they die; Keratin remains inside the cell
