ANATOMY

Detailed explanation-1: -When the urinary bladder fills with urine, the bladder wall stretches to accommodate the increased volume. In the distended bladder, the urothelium reorganizes into two or three layers without any structural damage. Due to this transitional ability of the urothelium, it is also known as the transitional epithelium.

Detailed explanation-2: -The main function of transitional epithelium is to allow tissue to expand and contract. For example, the transitional epithelium lines the inner walls of the urinary bladder, and this tissue allows the bladder to expand when the bladder fills with urine.

Detailed explanation-3: -Urothelium or transitional epithelium. This is the layer of cells that lines the inside of the kidneys, ureters, bladder, and urethra.

Detailed explanation-4: -Tight junctions are observed in the epithelium of the urinary bladder, preventing the escape of fluids comprising the urine. An anchoring junction provides a strong yet flexible connection between epithelial cells. There are three types of anchoring junctions: desmosomes, hemidesmosomes, and adherens.

Detailed explanation-5: -Transitional epithelium: A transitional epithelium (also known as urothelium) is made up of several layers of cells that become flattened when stretched. It lines most of your urinary tract and allows your bladder to expand.
