Drawing of skin structure



The outermost, nonsensitive layer of Skin in an animal or a plant. Epidermis, or Cuticle, covers the middle Dermis (cutis, corium) layer while the innermost layer is known as the Hypodermis (subcutis). In humans, the epidermis is composed of four layers, which are (from the outside):

1) a layer of dead, horny, flattened cells that form a continuous membrane,

2) a layer of oily transparent cells,

3) one or more layers of granular cells and

4) a layer of rounded pigmented cells.

The epidermis provides protection from water, sunlight, dirt, bacteria, and other potentially dangerous materials. In dehairing processes, the epidermis is attacked by enzymes or alkalis.
