Transitional epithelium
From WikiMD's WELLNESSPEDIA
(Redirected from Urothelium)
Stratified epithelium that changes shape from cuboidal to squamous when stretched without losing strength or consistency.
Histology[edit]
Arrangement consists of several layers of closely packed, flexible and easily stretched cells.
Transitional epithelium in bladder[edit]
When the surfaces of the cells are stretched, as in a full bladder, the cells appear squamous or flat but when the tissue is relaxed, as in an empty bladder, the layers of cells look ragged like the teeth of a saw.
Distribution[edit]
Transitional epithelium lines the pelvis of the kidney, the ureters, the urinary bladder, and the upper part of the urethra.
