Where does keratinization occur?

Understand the Problem

The question is asking about the specific locations in the body where keratinization occurs. Keratinization is the process where keratin, a protective protein, is produced in the skin, hair, and nails, among other areas.

More Information

Keratinization occurs in the epidermis where keratinocytes move through its layers and get transformed into corneocytes, which are ultimately shed from the skin surface.

Tips

A common mistake is to confuse keratinization with processes occurring in other parts of skin like the dermis or in other tissues like nails or hair.
