The two major layers of the skin are the outer lambaste and the internal dermis. Epidermis- make of stratified squamous epithelium; cells called ceratinocytes. 1. Stratum Germanitivum- the inner most layer where mitosis takes place; new cells produce keratin and die as they are pushed to the surface. 2. Stratum Corneum- the outermost layers of dead(a) cells; keratin prevents loss and entry of water and resists entry of pathogens and chemicals. 3.
Langerhans Cells- phagocytize extraneous cloth and stimulate an immune response by lymphocytes. 4. Melanocytes- in the subvert epidermis, produce melanin.
