APPLIED RADIOLOGICAL ANATOMY

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 outermost layer of the epidermis, and is comprised of dead skin cells. It protects the living cells beneath it by providing a tough barrier between the environment and the lower layers of the skin.

Detailed explanation-3: -The epidermis is made up of several layers which are formed through mitosis. However, as these move up in strata, the outermost layers get filled with keratin and eventually the outer layer is made up of dead cells.

Detailed explanation-4: -It is made up of dead skin cells filled with a tough protein called keratin. It serves as a hard protective layer against environmental trauma, such as abrasions, light, heat, chemicals, and microorganisms.
