Keratin - Wikipedia Keratin ( ˈkɛrətɪn [1][2]) is one of a family of structural fibrous proteins also known as scleroproteins It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin in vertebrates Keratin also protects epithelial cells from damage or stress
Keratinized Tissue in the Human Body: Functions and Benefits Keratinized tissue consists of stratified squamous epithelial cells that undergo keratinization, accumulating keratin proteins and losing their nuclei as they migrate toward the surface This process creates a dense, protective layer that enhances resilience against mechanical stress and environmental exposure
Difference Between Keratinized and Non-Keratinized Epithelium Non-Keratinized Epithelium The non-keratinized epithelium is a type of stratified squamous epithelium that lacks the protein keratin in the cells Unlike keratinized epithelium, it is found in areas of the body that are not subjected to friction, abrasion, and trauma, such as the oral mucosa, esophagus, and vagina
Keratinized Epithelium - BYJUS Keratin is a fibrous protein that makes the outermost skin in most vertebrates They are the key structural elements of hairs, nails, scales, horns, feathers, hooves and claws They protect the epithelial cells from stress or damage Also Read: Epithelial Tissue and Connective Tissue
