ANATOMY

Detailed explanation-1: -The ureteric wall is composed of three main of tissue: inner mucosa, middle muscle layer and outer serosa. The lining of the inner layer is transitional epithelium. Deeper to it is the lamina propria, which is combined with the epithelium make up the mucosal lining.

Detailed explanation-2: -The wall of the ureter consists of three layers. The outer layer, the fibrous coat, is a supporting layer of fibrous connective tissue. The middle layer, the muscular coat, consists of the inner circular and outer longitudinal smooth muscle. The main function of this layer is peristalsis: to propel the urine.

Detailed explanation-3: -Mucous membrane (mucosa) transitional epithelium; lines the renal pelvis, ureters, bladder, and urethra.

Detailed explanation-4: -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-5: -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.
