Transitional cell
Transitional cell
Transitional cell (/trænˈzɪʃənəl sɛl/), also known as urothelial cell, is a type of cell found in the urinary system, specifically in the bladder, ureters, and renal pelvis. These cells have the unique ability to stretch and return to their normal shape without damage, a characteristic that allows them to accommodate the fluctuating volumes of urine.
Etymology
The term "transitional" is derived from the Latin word "transitio", which means "going across" or "passing over". This refers to the cells' ability to change shape and adapt to the varying volumes of urine. The term "cell" comes from the Latin "cella", meaning "small room".
