Now these four different types of cells found in the epidermis are spread among the five different layers found within the epidermis. So we can actually subdivide our epidermis into five different layers. So these layers go as follows. The lowest layer in the epidermis is the stratum basal. The next layer is the stratum spinosum, followed by the stratum granolasum, followed by the stratum lucidum, followed by the stratum corneum. Now stratum simply is another word for layer.
