Intermediate Head of the Pancreas Quiz

Q1. Which artery supplies the superior part of the pancreatic head through pancreaticoduodenal branches?

• Inferior mesenteric artery
• Left gastric artery only
• Middle colic artery only
• Gastroduodenal artery

Q2. Which artery supplies the inferior part of the pancreatic head through pancreaticoduodenal branches?

• Inferior mesenteric artery
• Cystic artery
• Splenic artery
• Superior mesenteric artery

Q3. Why are the pancreaticoduodenal arterial arcades anatomically important?

• They form the main pancreatic duct
• They connect the portal vein directly to the aorta
• They drain bile into the duodenum
• They connect celiac and superior mesenteric arterial territories

Q4. Where is the portal vein usually formed relative to the pancreas?

• Inside the gallbladder
• Within the pancreatic tail
• Anterior to the stomach
• Posterior to the pancreatic neck

Q5. How does the uncinate process relate to the superior mesenteric vessels?

• It lies entirely within the vessels
• It is always anterior to the pancreatic neck and vessels
• It lies in the splenic hilum
• It lies posterior to the superior mesenteric vessels

Q6. Which embryonic pancreatic bud forms the uncinate process and part of the pancreatic head?

• Ventral pancreatic bud
• Splenic primordium
• Hepatic diverticulum alone
• Dorsal pancreatic bud alone

Q7. Which embryonic bud contributes the remaining larger portion of the pancreatic head?

• Ventral pancreatic bud only
• Caudal hepatic bud
• Dorsal pancreatic bud
• Ureteric bud

Q8. Which lymph node groups commonly receive lymph from the pancreatic head?

• Pancreaticoduodenal nodes
• Popliteal nodes
• Axillary nodes
• Superficial inguinal nodes

Q9. Why can pathology of the pancreatic head cause biliary obstruction?

• The bile duct is separated from the pancreas by the spleen
• The cystic duct passes through the pancreatic tail
• The hepatic veins lie within the pancreatic head
• The distal common bile duct is closely related to the pancreatic head

Q10. Which venous channels drain the pancreatic head and duodenum toward the portal system?

• Pulmonary veins
• Great saphenous vein
• Azygos vein only
• Pancreaticoduodenal veins
