Stratified squamous, nonkeratinized epithelium
This electron micrograph of the lining of the esophagus shows the structure of the superficial-most cells. In this epithelium, the surface cells are living and possess a variety of organelles, as well as a prominent nucleus. The cells in this image are in the process of being sloughed from the surface of the epithelium. 6000x
