GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -The epidermis is composed of keratinized, stratified squamous epithelium. It is made of four or five layers of epithelial cells, depending on its location in the body.

Detailed explanation-3: -The epidermis primarily consists of keratinocytes (proliferating basal and differentiated suprabasal), which comprise 90% of its cells, but also contains melanocytes, Langerhans cells, Merkel cells, and inflammatory cells. Epidermal thickenings called Rete ridges (or rete pegs) extend downward between dermal papillae.
