Urinary bladder

The mucosa of the bladder has a histologic appearance very similar to that of the ureter. Transitional epithelium has characteristic dome-shaped cells at the surface when the bladder is not distended with urine. Dome cells are often bi-nucleated and become flattened when the bladder is distended. A connective tissue layer (lamina propria continuous with submucosa) underlies this epithelium. 400x
