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 inner lining of the urinary bladder is a mucous membrane of transitional epithelium that is continuous with that in the ureters. When the bladder is empty, the mucosa has numerous folds called rugae. The rugae and transitional epithelium allow the bladder to expand as it fills.

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: -The transitional epithelium of the urinary tract is lined by a layer of glycosaminoglycans (GAGs) that function to prevent microbial and crystal adherence to the bladder epithelium and minimize the movement of urine solutes and proteins through the bladder epithelium.

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.
