#10 The epidermis has several layers of cells which begin at the junction of the dermis and end at the surface. As the cells progress through the layers, they change in morphology depending on their state of activity. Those in the deepest layers are the most metabolically active while those at the surface have ceased functioning and form a protective layer of keratin.
From the internal junction with the dermis to the external surface the layers of thick skin are:
1. stratum basale (also called stratum germinativum)
2. stratum spinosum
3. stratum granulosum
4. stratum lucidum
5. stratum corneum.
