Urinary bladder histology

Renal Pelvis, Ureter, And Bladder Renal Pelvis The entire urine collecting system is lined by a sheet of transitional epithelium known as urothelium. In the renal pelvis, the urothelial cells are two or three layers thick. The most superficial cells are larger than the others and send projections down over the lateral surfaces of the cells beneath them, sometimes having an umbrella-like appearance. These “umbrella cells” have abundant eosinophilic cytoplasm and may be binucleate. Underneath…

This epithelium is found lining the urinary bladder, ureters and urethra, as well as in the ducts of the prostrate gland

Transitional epithelium is a stratified tissue made of multiple cell layers, where the cells constituting the tissue can change shape depending on the distention in the organ. When the organ is filled with fluid, cells on the topmost layer of this epithelium can stretch and appear flattened

This tissue consists of multiple layers of epithelial cells which can contract and expand in order to adapt to the degree of distension needed. Transitional epithelium lines the organs of the urinary system and is known here as urothelium.
