Skin histology
Make it clearer
Picture a cross section of skin viewed from the surface downward. First comes the epidermis, a stratified squamous epithelium: a covering made of four or five strata, depending on the location. Its keratinocytes, the cells of this covering, mature as they move from the basal layer to the cornified surface.
Below it lies the dermis. This is a network made mostly of collagen fibers, with some elastic fibers produced by fibroblasts. Blood vessels and nerves run through this network, which also contains sweat glands and hair follicles.
