Detailed explanation-1: -The layers of the epidermis include the stratum basale (the deepest portion of the epidermis), stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum (the most superficial portion of the epidermis).
Detailed explanation-2: -The stratum corneum is the outer layer of the skin (epidermis). It serves as the primary barrier between the body and the environment. The epidermis is made up of five layers: stratum basale: the deepest layer of epidermis, made up of cuboidal and columnar cells.
Detailed explanation-3: -The stratum corneum is the outermost layer of the epidermis and marks the final stage of keratinocyte maturation and development. Keratinocytes at the basal layer of the epidermis are proliferative, and as the cells mature up the epidermis, they slowly lose proliferative potential and undergo programmed destruction.
