Detailed explanation-1: -The top layer of the epidermis. This is the layer of the epidermis that you see. In the stratum corneum, keratinocytes become corneocytes (corn-ee-o-site). Corneocytes are strong, dead keratinocytes, and they protect you from harm, including abrasions, light, heat and pathogens.

Detailed explanation-2: -Keratinocytes are the predominant cell type of epidermis and originate in the basal layer, produce keratin, and are responsible for the formation of the epidermal water barrier by making and secreting lipids.

Detailed explanation-3: -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-4: -Stratum Corneum The keratinocytes in this layer are called corneocytes. They are devoid of almost all of their water and they are completely devoid of a nucleus at this point. They are dead skin cells filled with the tough protein keratin. In essence, they are a protein mass more so than they are a cell.
