Corneocytes
Corneocytes (pronunciation: /kɔːrˈniːəˌsaɪts/) are the final product of Keratinocyte differentiation in the Stratum corneum, the outermost layer of the epidermis.
Etymology
The term "corneocyte" is derived from the Latin word "corneus," meaning "horny," and the Greek word "kytos," meaning "cell." This name reflects the cell's hard, horn-like nature, which is due to the high concentration of Keratin within the cell.
Structure and Function
Corneocytes are anucleate cells, meaning they lack a nucleus. They are filled with keratin and surrounded by a protein envelope, which is further surrounded by a lipid envelope. This structure makes corneocytes highly resistant to environmental damage and allows them to serve as a protective barrier for the body.
Corneocytes also play a crucial role in the process of Desquamation, the shedding of dead skin cells. This process helps to maintain the health and integrity of the skin.
