Esophagus-Nonkeratinizing stratified squamous epithelium

stratified squamous epithelium: consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane; ex: skin; simple epithelium would only be one cell thick

Transitional epithelium resembles stratified squamous, but the surface cells are rounded. This epithelium is only found in the ureter and bladder. It is unique because it changes from round to flat, causing expansion of overall tissue. This process is how we urinate. When the bladder is expanded, the cells resemble squamous (flat) cells. When the bladder is empty, the cells resemble cuboidal cells.
