NEET PG DENTAL EXAM

Detailed explanation-1: -The bladder is a subperitoneal, hollow muscular organ that acts as a reservoir for urine.

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: -The ureter (one per kidney) is a long, straight, muscle-walled tube. The epithelium lining this tube is stratified, transitional epithelium.

Detailed explanation-4: -The inner mucosa is lined with transitional epithelium and scattered goblet cells that secrete protective mucus. The muscular layer of the ureter consists of longitudinal and circular smooth muscles that create the peristaltic contractions to move the urine into the bladder without the aid of gravity.
