The epidermis contains no blood vessels, and is nourished by diffusion from the dermis. The main type of cells which make up the epidermis are keratinocytes, melanocytes, Langerhans cells and Merkels cells. The epidermis helps the skin to regulate body temperature.
Name the four types of cells found in the epidermis. Keratinocytes, Langerhans cells or epidermal dendritic cells, Merkel cells or tactile cells and melanocytes. Keratinocytes are most abundant. A Merkel cell or a tactile cell is connected to neurons and senses touch in the skin. The Merkel cell is found in the stratum basale.
