Intermediate Ureters Quiz

Q1. Which three regions are classically described as ureteric constrictions?

• Major calyx, renal artery, and bladder neck
• Ureteropelvic junction, iliac vessel crossing, and ureterovesical junction
• Renal cortex, renal medulla, and bladder apex
• Renal papilla, renal hilum, and urethra

Q2. How does the ureter enter the urinary bladder?

• Obliquely through the bladder wall
• Vertically through the bladder dome
• Through the prostate in both sexes
• Through the urethral lumen

Q3. What is the functional importance of the oblique intramural ureter?

• It filters blood
• It produces urine
• It helps prevent vesicoureteral reflux
• It forms the bladder sphincter

Q4. What is the main muscular arrangement in the upper ureter?

• No muscular layer
• Only circular skeletal muscle
• Inner longitudinal and outer circular smooth muscle
• Inner skeletal and outer cardiac muscle

Q5. What outer connective-tissue layer surrounds the ureter?

• Renal capsule
• Adventitia
• Serosa along its entire length
• Endocardium

Q6. Which arteries can contribute to the blood supply of the abdominal ureter?

• Pulmonary arteries only
• Renal, gonadal, aortic, and iliac arterial branches
• Carotid arteries only
• Coronary arteries only

Q7. How are ureteric arteries arranged near the ureter?

• They enter only at the ureteric orifice
• They travel only inside the lumen
• They form longitudinal anastomoses in the adventitia
• They form glomeruli in the ureter

Q8. Which autonomic plexuses contribute fibers to the abdominal ureter?

• Brachial and cervical plexuses
• Cardiac plexus only
• Renal, aortic, and superior hypogastric plexuses
• Lumbar somatic plexus only

Q9. In the female pelvis, what important relationship does the ureter have to the uterine artery?

• The ureter passes inferior to the uterine artery
• The ureter always passes superior to the uterine artery
• The ureter lies inside the uterus
• The ureter passes through the uterine artery

Q10. In the male pelvis, which structure crosses superior to the ureter near the bladder?

• Testicular artery
• Ductus deferens
• Round ligament of the uterus
• Urethra
