An epithelial tissue has multiple layers, flat and irregular cell shape, dead outer layers of cells, and keratin present in some
Rudik [331]

This is stratified keratinized squamous epithelium.

<h3>What are the characteristics of stratified keratinized squamous epithelium?</h3>
  • A kind of stratified squamous epithelium known as keratinized stratified squamous epithelium has cells that have multiple layers of thick keratin in the apical portion of the cells.
  • Skin and underlying tissues can benefit from the stiff, fibrous intracellular protein keratin's ability to protect them from heat, bacteria, and chemicals.
  • In the process of keratinization, the cells build up keratin as they ascend, transforming into thin, metabolically inert pockets of keratin devoid of nuclei.
  • As cells distance themselves from the nutritive blood supply and the organelles eventually perish, the relative amount of keratin in the cells rises.
  • The cells on the top layer lose all function as a result of keratinization and are now primarily involved in protecting against mechanical stress and dehydration.
