MICROANATOMY

Detailed explanation-1: -Lining epithelium: The urinary bladder lining is a specialized stratified epithelium, the urothelium. The urothelium is exclusively in urinary structures such as the ureter, urinary bladder, and proximal urethra.

Detailed explanation-2: -Urinary bladder and urethra are consisting of epithelium on the lumen surrounded by a collagen rich connective tissue and muscle layer.

Detailed explanation-3: -In the urethra, there will be two types of epithelium. The proximal epithelium is transitional epithelium (uroepithelium). These cells appear columnar near the basement membrane and become more rounded and dome-shaped towards the lumen.

Detailed explanation-4: -The transitional epithelium, also known as the urothelium, lines the urethra, ureters, and urinary bladder. The transitional epithelium that lines the prostatic urethra of the male reproductive system is connected with the urothelium of the urinary bladder.
