Detailed explanation-1: -Keratinized stratified squamous epithelium is identified by the multiple layers of dead cells at the surface. Keratin accumulation within maturing cells effectively waterproofs the cells, blocking diffusion of nutrients and wastes. The cells subsequently die.
Detailed explanation-2: -The epidermis is the thin outer layer of the skin. It consists of 2 primary types of cells: Keratinocytes. Keratinocytes comprise about 90% of the epidermis and are responsible for its structure and barrier functions.
Detailed explanation-3: -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-4: -In the epidermis of skin in mammals, reptiles, and birds, the layer of keratin in the outer layer of the stratified squamous epithelial surface is named the stratum corneum. Stratum corneum is made up of squamous cells which are keratinized and dead. These are shed periodically.
