Difference between Keratinized and Non-keratinized Epithelial Tissues

Epithelium constitutes the outer layer of body surfaces, linings of the alimentary canal and the walls of hollow structures. It covers the internal or external surfaces of the body. The functions epithelial tissue is to protect the underlying tissues from physical damages, infection, desiccation, UV radiation and heat loss. Based on the presence of Keratin, the epithelial tissues are categorized into Keratinized epithelium and Non-keratinized epithelial tissues. Keratins are a diverse group of structural proteins that form the intermediate filament network and they provide the structural integrity of keratinized epithelial cells.

The present post discusses the Difference between Keratinized and Non-keratinized Epithelial Cells.
