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.

Detailed explanation-2: -The stratum disjunctum is the uppermost and loosest layer of skin. The stratum compactum is the comparatively deeper, more compacted and more cohesive part of the stratum corneum. The corneocytes of the stratum disjunctum are larger, more rigid and more hydrophobic than that of the stratum compactum.

Detailed explanation-3: -The stratum corneum is composed of several layers of flattened, keratin-containing dead cells known as squames. The most superficial layer of skin, thestratum corneum, is composed of as many as 20 layers of flattened, keratinized cells with a thickened plasmalemma (Figs. 14.2, 14.5–14.7).
