May 5, 2024 · The ureteral wall comprises 3 main tissue layers: the inner mucosa, middle muscle layer, and outer serosa. Stratified transitional epithelium lines the inner ureteral mucosal lining. Deep to this structure is a relatively thick, fibroelastic lamina propria.

Jan 26, 2024 · A ureteral obstruction is a blockage in one or both of the tubes (ureters) that carry urine from the kidneys to the bladder. Ureteral obstruction can be cured.

May 22, 2024 · Ureters connect the kidneys to the bladder. The kidneys are two organs situated just below the ribs that filter and dispose of waste from the body in the form of urine. The bladder is a hollow, muscular organ located in the pelvis that serves as a receptacle for urine.

Peristaltic contraction of the smooth muscle moves urine from the kidney to the bladder. Histology of the ureter - transitional epithelium (umbrella cells), lamina propria, muscularis externa, and adventitia.

The ureters are two tubes that are made out of smooth muscle and transitional epithelial tissues, which are a type of epithelial tissue that may either be columnar or squamous. Each kidney has its own ureter through which urine drains into. Human urinary system: 1) Human urinary system. 2) Kidney. 3) Renal pelvis. 4) Ureter. 5) Urinary bladder.
