GENERAL HISTOLOGY

Detailed explanation-1: -The stratum corneum is the outermost layer of the epidermis, and is made up of 10 to 30 thin layers of continually shedding, dead keratinocytes. The stratum corneum is also known as the “horny layer, ” because its cells are toughened like an animal’s horn.

Detailed explanation-2: -The human stratum corneum comprises 15 or so layers of flattened corneocytes and is divided into two layers: the stratum compactum and the stratum disjunctum. The stratum compactum is the deep, dense, cohesive layer, while the stratum disjunctum is looser and lies superficially to the stratum compactum.

Detailed explanation-3: -The stratum corneum functions to form a barrier to protect underlying tissue from infection, dehydration, chemicals and mechanical stress. Desquamation, the process of cell shedding from the surface of the stratum corneum, balances proliferating keratinocytes that form in the stratum basale.

Detailed explanation-4: -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.
