Transitional epithelium is a specialized form of stratified skin tissue. It is often called urothelial epithelium because the lining of the urinary tract is the most common place to find it. Transitional epithelium is very different from other types of epithelium because its cells are able to change shape to increase the amount of stretching the tissue can withstand. This ability to change shape is the reason it is referred to as transitional as the cells transition from one shape to another.
