Layers of the Epidermis. The epidermis of thick skin has five layers. Beginning at the basal lamina and traveling superficially toward the epithelial surface, we find the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. Refer to Figure 2 as we describe the layers in a section of thick skin. Stratum Basal Epidermis, in zoology, protective outermost portion of the skin.There are two layers of epidermis, the living basal layer, which is next to the dermis, and the external stratum corneum, or horny layer, which is composed of dead, keratin-filled cells that have migrated outward from the basal layer.The melanocytes, responsible for skin colour, are found in the basal cells
Stratum corneum is the outermost layer of the epidermis. It consists of 10 to 30 layers of dead keratinocytes that are constantly being shed. Shedding of these cells slows significantly with age. The complete cell turnover, from basal cell to stratum corneum, takes around four to six weeks for young adults and about a month and a half for older. The epidermis, which is the topmost layer, actually has 5 sub-layers. The stratum basale is the deepest layer, while the stratum corneum is the outermost layer of epidermis. Bodytomy takes a closer look at these layers along with their functions
Epidermis Layers . It is basically outermost, thin skin layer that is perceptible by to the eye and its major function to provide protection to the body. It does not comprise of any blood vessels.
