PATHOLOGY

Detailed explanation-1: -The stratum corneum, which is the outermost epidermal layer, consists of dead cells and is the major barrier to chemical transfer through the skin.

Detailed explanation-2: -The stratum corneum is the outermost layer of the epidermis and is composed of dead scale-like cells that become progressively flattened and joined together.

Detailed explanation-3: -Remember that there are no blood vessels in the epidermis so the cells get their nutrients by diffusion from the connective tissue below, therefore the cells of this outermost layer are dead. Stratum Corneum cells flake off.

Detailed explanation-4: -Stratum corneum is the only layer of skin we see with our eyes. It is made up of dead skin cells filled with a tough protein called keratin.
