GENERAL HISTOLOGY

Detailed explanation-1: -Epidermis, the epithelial layer of skin, is primarily protective. This layer, consisting of keratinized stratified squamous epithelium, is tough, relatively impermeable, and self-replacing. These functional qualities are conferred by the epidermis’ principal cell type, the keratinocyte.

Detailed explanation-2: -The epidermis consists of keratinized stratified squamous epithelium. Four cell types are present: Keratinocytes produce keratin, a protein that hardens and waterproofs the skin.

Detailed explanation-3: -The keratinised squames layer (stratum corneum) is the final layer. These are layers of dead cells, reduced to flattened scales, or squames, filled with densely packed keratin.

Detailed explanation-4: -The epidermis is composed of stratified squamous epithelium of the keratinized type. The epidermis shows no thinning during or after expansion. In fact, most studies have noted an increase in thickness during skin expansion. The active basal layer of the epidermis increases in density and thickness.
