The epidermis is the outermost layer of the skin, which is composed of cells called keratinocytes – made of a protein called keratin. Quiz: What is Anatomy and Physiology? The epidermis is the outermost layer of the skin, which is composed of cells called keratinocytes – made of a protein called keratin. The dermis is also the site where all the accessory structures of the skin – your hair, nails, and a variety of multicellular exocrine glands originate. The epidermis is the outermost of the three layers that make up the skin, the inner layers being the dermis and hypodermis. The outermost layer is the stratum corneum, which prevents water loss. Furthermore, the dermis is mesodermal in origin while the epidermis is ectodermal in origin. Ringkasan - Epidermis vs Dermis. Dermis: Dermis contains fibroblasts, adipocytes, and macrophages. Making new skin cells: This happens at the bottom of the epidermis. Reticular fibers 4. 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.
