Esophagus, unspecified source. Note the presence of some glands in submucosa.
This nonkeratinized, stratified squamous epithelium is similar to that lining the inside of your cheek (i.e., the buccal mucosa). Such an epithelium provides a ready source of living cells, e.g. for DNA samples. More on epithelial tissue.
This mucosal epithelium differs from the epidermis of skin primarily by being non-keratinized, also by lacking various specialized features of skin, such as sweat glands and hair follicles.
