Q1. Which branch of the inferior pancreaticoduodenal artery participates in the anterior pancreaticoduodenal arcade?
- Jejunal branch
- Middle colic branch
- Posterior branch
- Anterior branch
Q2. Which branch participates in the posterior pancreaticoduodenal arcade?
- Right colic branch
- Posterior branch
- Anterior branch
- Ileal branch
Q3. Which vessel is the usual parent artery of the superior pancreaticoduodenal arteries?
- Superior mesenteric artery
- Inferior mesenteric artery
- Left colic artery
- Gastroduodenal artery
Q4. Why are the pancreaticoduodenal arcades anatomically important?
- They connect the renal and gonadal arteries
- They drain the pancreas into the portal vein
- They supply only the spleen
- They connect celiac and superior mesenteric territories
Q5. Which portion of the duodenum is most closely associated with the transition from celiac to superior mesenteric arterial supply?
- Pyloric canal
- Duodenal bulb only
- Second part of the duodenum near the major papilla
- Duodenojejunal flexure only
Q6. Which branch of the superior mesenteric artery may share a common origin with the inferior pancreaticoduodenal artery?
- Right colic artery
- Ileocolic artery
- Middle colic artery
- First jejunal artery
Q7. Which structure lies in close anatomical association with the inferior pancreaticoduodenal vessels as they supply the pancreatic head?
- Pancreaticoduodenal groove
- Renal pelvis
- Sigmoid mesocolon
- Splenic hilum
Q8. What happens to collateral flow through the pancreaticoduodenal arcades when proximal celiac arterial flow is markedly reduced?
- It must cease completely
- It may increase from the SMA toward the celiac territory
- It bypasses the pancreas through the renal artery
- It reverses only into the inferior mesenteric artery
Q9. Which artery is the most direct source of blood entering the inferior pancreaticoduodenal artery in typical anatomy?
- Proper hepatic artery
- Splenic artery
- Inferior mesenteric artery
- Superior mesenteric artery
Q10. Which statement best describes the arterial supply around the pancreatic head?
- It includes anterior and posterior pancreaticoduodenal arcades
- It is supplied only by the splenic artery
- It arises entirely from the inferior mesenteric artery
- It depends on one terminal artery without anastomoses
