Epidermis is made up of stratified epithelium.
Epidermis is made up of a thin layer of flat, thin and scale-like dead cells, which are a part of stratified epithelium. It is the outermost layer of the skin. The cells in this layer are called keratinocytes. The keratinocytes are composed of a protein called keratin. Keratin strengthens the skin and makes it waterproof.
Melanocytes that produce melanin are also present in this layer. In addition, Merkel cells essential for light-touch sensation and Langerhans cells, part of the immune system are also present on the skin.
