Study Notes
Skin Structure and Function
- The stratum basale, the innermost layer of the epidermis, is responsible for the production of melanin.
- Dermal papillae are small, nipple-like projections of the dermis that increase the surface area for exchange of oxygen and nutrients between the dermis and epidermis.
- The color of the skin is determined by the amount and type of melanin, a pigment produced by melanocytes in the stratum basale.
- The dermal layer, the layer of skin beneath the epidermis, is responsible for the structure and function of hair.
- Melanin transfer is the process by which melanin is transferred from melanocytes to epithelial cells, resulting in skin pigmentation.
