Question

The outer layer of skin is formed by

Answer 1

The outer layer of the skin is called the epidermis. This layer is formed by epithelial cells. The dead layer of cells is called the stratum corneum.

Answer 2

Answer: Squamous epithelial cells

Explanation: Squamous epithelial cells form the outer layer of skin, but they serve much more than a cosmetic role. Your skin protects against invasion from bacteria and other infectious organisms. Throughout life, you collect a thin film of bacteria on your skin. If these squamous epithelial cells didn’t form a tough barrier, the bacteria would penetrate the skin and invade your body. Disorders in which this barrier is lost—such as in burns—can place an individual at great risk for infection.
