• Inferior mesenteric artery only
• Celiac trunk
• Median sacral artery

Q2. The right inferior phrenic artery passes in close relation to which major venous structure?

• Left gonadal vein
• Inferior mesenteric vein
• Splenic vein
• Inferior vena cava

Q3. Which branch of an inferior phrenic artery supplies the suprarenal gland?

• Middle suprarenal artery
• Superior suprarenal artery
• Inferior suprarenal artery
• Renal segmental artery

Q4. The inferior phrenic arteries commonly divide into which terminal branches on the diaphragm?

• Medial and lateral branches

Q9. Which feature distinguishes the superior suprarenal arteries from the middle suprarenal arteries?

• Middle suprarenal arteries arise from the celiac trunk
• Superior suprarenal arteries arise from the renal artery
• Middle suprarenal arteries arise from the inferior phrenic artery
• Superior suprarenal arteries arise from the inferior phrenic artery

Q10. Where are the inferior phrenic arteries positioned relative to their diaphragmatic target after arising near the upper abdominal aorta?

• They enter the mesentery of the small intestine
• They ascend toward the diaphragm
• They pass through the inguinal canal
