skinThe outer layer of your skin (the epidermis) is made of stratified squamous epithelial cells. Stratified cuboidal epithelium: This type of epithelium is not as common and is found in the excretory ducts of your salivary and sweat glands.
Lesson Summary. Stratified squamous epithelium is a type of tissue found covering and lining parts of the body. In this tissue, cells are flattened, joined tightly together, and stacked. The major function of this tissue type is protection, as it is found in areas that undergo wear-and-tear.
Stratified squamous epithelium is located in the oral cavity and esophagus.
Examples of keratinized stratified squamous epithelium include skin, epidermis of the palm of the hand and sole of the foot, and the masticatory mucosa.
Stratified squamous epithelial cells are found in a number of organs, including the skin epidermis and the thymus.
The type of epithelium covering these surfaces is a keratinized or para-keratinized stratified squamous epithelium, which provides the masticatory mucosa its capacity to better support the stress upon which it is subjected during mastication.
Simple squamous epithelia are found lining the cavities of the body including the pericardial, pleural, and peritoneal cavities, or in areas where passive diffusion occurs, such as glomeruli in the kidney and alveoli in the respiratory tract.
Simple squamous epithelia are found in endothelium (lining of blood and lymph capillaries), mesothelium (coelomic epithelium/peritoneum), alveoli of lungs, glomeruli, and other tissues where rapid diffusion is required.
The simple squamous epithelium location specifically exists in the lining of the blood vessels like the arteries, veins, and capillaries. It is also found lining the alveoli or air sacs within the lungs of a living and breathing human being.
Stratified squamous epithelium consists of a single basal layer containing stem cells, 2–3 layers of proliferative basaloid cells in the suprabasal region, and larger keratinized cells toward the surface. The esophageal squamous epithelium is nonkeratinizing, i.e., it does not have a stratum corneum.
Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. An example is the epidermis, the outermost layer of the skin. There are three principal shapes of epithelial cell: squamous, columnar, and cuboidal.
