Intermediate Head of the Pancreas Quiz

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

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

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

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

Q3. Why are the pancreaticoduodenal arterial arcades anatomically important?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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