GENERAL HISTOLOGY

Detailed explanation-1: -Urinary bladder and urethra are consisting of epithelium on the lumen surrounded by a collagen rich connective tissue and muscle layer. The epithelial layer serves as a barrier that prevents the urine from sweeping into the body cavity.

Detailed explanation-2: -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-3: -Transitional epithelium is a layer of cells that forms the mucosal lining of your ureters, a portion of your urethra, and your urinary bladder. These cells are called transitional because they can undergo a change in their shape and structure.

Detailed explanation-4: -Transitional Epithelium Examples The urothelium is the most common form of transitional epithelium. The transitional epithelium, also known as the urothelium, lines the urethra, ureters, and urinary bladder.
