MICROANATOMY

Detailed explanation-1: -The stratum corneum is the most superficial layer of the epidermis and is the layer exposed to the outside environment (see Figure 5.1. 4). The increased keratinization (also called cornification) of the cells in this layer gives it its name. There are usually 15 to 30 layers of cells in the stratum corneum.

Detailed explanation-2: -The stratum corneum, which is the outermost epidermal layer, consists of dead cells and is the major barrier to chemical transfer through the skin. Although nonpolar chemicals cross the skin by diffusion through the stratum corneum, no active transport exists in the dead cells of this…

Detailed explanation-3: -Stratum corneum is the only layer of skin we see with our eyes. It is made up of dead skin cells filled with a tough protein called keratin. It serves as a hard protective layer against environmental trauma, such as abrasions, light, heat, chemicals, and microorganisms.
