Intermediate Renal Arteries Quiz

Q1. What is the usual anterior-to-posterior arrangement of the major structures at the renal hilum?

• Vein, artery, pelvis
• Pelvis, artery, vein
• Vein, pelvis, artery
• Artery, vein, pelvis

Q2. Which artery passes posterior to the inferior vena cava?

• Right renal artery
• Left renal artery
• Inferior mesenteric artery
• Left gonadal artery

Q3. The left renal artery is usually related superiorly to which vessel arising from the abdominal aorta?

• Common iliac artery
• Median sacral artery
• Inferior mesenteric artery
• Superior mesenteric artery

Q4. Why are renal segmental arteries clinically important during partial nephrectomy?

• They supply only the renal capsule
• They are largely end arteries
• They always anastomose freely with adjacent segments
• They drain directly into the renal vein

Q5. Which term describes an additional renal artery that reaches a kidney in addition to the main renal artery?

• Portal renal artery
• Terminal iliac artery
• Median renal artery
• Accessory renal artery

Q6. What is a polar renal artery?

• A branch confined to the suprarenal gland
• An artery entering a renal pole outside the hilum
• An artery supplying only the renal pelvis
• A vein accompanying the ureter

Q7. An inferior polar renal artery may have an important relationship with which structure?

• Ureteropelvic junction
• Portal vein
• Pancreatic duct
• Common bile duct

Q8. Which branches arise from segmental arteries within the renal sinus?

• Arcuate veins
• Interlobar arteries
• Lumbar arteries
• Inferior phrenic arteries

Q9. Where do interlobar arteries travel within the kidney?

• Within the renal columns between pyramids
• Along the renal vein outside the kidney
• Inside the ureter
• Only within the fibrous capsule

Q10. Which arteries arise from interlobar arteries near the corticomedullary junction?

• Gonadal arteries
• Arcuate arteries
