Explanation:
Detailed explanation-1: -The stratum corneum is the outermost layer of the epidermis, and is made up of 10 to 30 thin layers of continually shedding, dead keratinocytes.
Detailed explanation-2: –1-the stratum basale (or stratum germinativum): Ten to 25% of cells found here are melanocytes: their long branching processes extend in between epidermal cells and reach into the more superficial Stratum spinosum.
Detailed explanation-3: -Stratum corneum The uppermost layer of the epidermis consists of 25 to 30 layers of flattened, dead keratinocytes that were transformed into corneocytes. Corneocytes are thin, flat, plasma membrane-enclosed packages of keratin that no longer contain a nucleus or any internal organelles.
