Homo sapiens skin epidermis Wikipedia:Epidermis_(skin) EMAPA:17528 EFO:0000954 skin CALOHA:TS-0283 GAID:932 The outer epithelial layer of the external integument of the body that is derived from the embryonic epiblast.[AAO] TAO:0000105 Zebrafish epidermis consists only of living cells unlike terrestrial vertebrates in which dead, keratinized cells are present. In terrestrial vertebrates the epidermis often forms an outer keratinized or cornified layer, the stratum corneum. Interaction between the epideris and dermis gives rise to feathers (birds), hair and mammary glands (mammals), teeth and scales (placoid: chondrichthyans; cosmoids, ganoid, cycloid in bony fishes). The outer epithelial layer of the skin that is superficial to the dermis.

The ancestor of all metazoans likely had an epidermis with a basal extracellular matrix (ECM), an apical extracellular glycocalyx, and one cilium with a striated rootlet per cell.[well established][VHOG] ZFA:0000105 EV:0100153 A cellular, multilayered epithelium derived from the ectoderm.
