Question
The first three strata of the epidermis consists of ______ keratinocytes and the most superficial strata contain ______ keratinocytes.Multiple choice question.dead; livingliving; dead
Solution
The correct answer is "living; dead". The first three strata of the epidermis (Stratum Basale, Stratum Spinosum, and Stratum Granulosum) consist of living keratinocytes. These cells are actively dividing and producing keratin, a type of protein. As they move up to the surface of the skin, they die and become part of the Stratum Corneum, the most superficial layer of the epidermis, which consists of dead keratinocytes. These dead cells provide a tough, protective layer for the skin.
