Touch device users, explore by touch or with swipe gestures. A typical example of stratified squamous keratinized epithelium is the epidermis. Underlying cell layers can be made of cuboidal or columnar cells as well.
Examples of epithelial tissues include the cells that make up the external layer of the human skin and the stomach lining.
Keratinized epithelium may cause hardening of the cells of the stomach lining. In the deep layer of stratified squamous epithelium, you will find the columnar epithelium that rests on the basement membrane. Notice how the simple columnar cells lining the uterine cervix transitions to stratified squamous epithelium. Start studying epithelial tissue images and drawings.
