View Epidermis Background. Dermis and epidermis are basically protective outer layers the epidermis of animals is made up of stratified layers of flattened cells. It does not contain any blood vessels and is, therefore.
Although the epidermis is ectodermal in origin, cells from other sources migrate into the epidermis. The skin serves many purposes. Stem cells, keratinocytes, melanocytes, merkel cells.
The epidermis thickness varies from 0.05 mm on the eyelids to 0.8±1.5 mm on the soles and palms.
Epidermis has many layers of cells, forming a stratified squamous epithelium. Furthermore, stratum basale is the deepest epidermal cell layer. An epithelium is avascular, meaning it lacks blood vessels. Borrowed from latin epidermis, from ancient greek ἐπιδερμίς (epidermís), ἐπί (epí, on top of) + δέρμα (dérma, skin).
