Did you know?

Epidermis includes the Greek prefix epi-, meaning "outer;" thus, the epidermis overlies the dermis, or inner layer of skin. The epidermis itself consists of four or five layers; the outermost layer is made of dead cells, which are being shed continuously. The epidermis acts as a physical barrier—a protective wrap over the body's surface, which, by preventing water loss, allows vertebrates to live on land.
