Stratified squamous, nonkeratinized epithelium
Stratified epithelia have multiple layers and are further classified by the shape of the cells at the surface. In stratified squamous epithelia, cells flatten as they are pushed from basal to surface layers. Surface cells are living, with visible nuclei. A layer of keratin does not form and the epithelium remains moist. Esophagus 400x
