Intermediate Neck of the Pancreas Quiz

Q1. Why is the pancreatic neck an important landmark for the portal venous system?

• The inferior vena cava begins behind it
• The hepatic veins form within it
• It contains the splenic venous origin
• The portal vein usually forms directly behind it

Q2. How does the superior mesenteric vein relate to the pancreatic neck?

• It lies only anterior to the stomach
• It runs within the main pancreatic duct
• It ascends posterior to the neck toward the portal confluence
• It terminates in the inferior vena cava

Q3. How does the splenic vein relate to the neck of the pancreas?

• It drains directly into the hepatic veins
• It lies within the cystic duct
• It approaches posteriorly from the left and joins the superior mesenteric vein
• It crosses the anterior abdominal wall

Q4. What is the relationship of the superior mesenteric artery to the pancreatic neck?

• It lies only along the superior border of the tail
• It is contained within the portal vein
• It passes through the pancreatic duct
• It passes posterior to the neck

Q5. Which structure typically lies posterior to the superior mesenteric vessels in the region inferior to the pancreatic neck?

• Uncinate process
• Gallbladder fundus
• Pancreatic tail
• Left hepatic lobe

Q6. Why is the neck useful as an imaging landmark?

• It lies inside the spleen
• It contains the inferior vena cava
• It is surrounded by lung tissue
• Its close relationship to the portal venous confluence provides a reproducible landmark

Q7. Which embryonic pancreatic bud contributes substantially to the region that becomes the neck and body?

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

Q8. What developmental event creates the unified pancreas near the neck-head region?

• Fusion of dorsal and ventral pancreatic buds after ventral bud rotation
• Fusion of the kidneys
• Closure of the urachus
• Rotation of the hindgut only

Q9. Why is the main pancreatic duct relevant to the neck?

• It is located only in the pancreatic tail
• It carries portal blood
• It passes through the neck toward the head
• It ends in the neck in normal anatomy

Q10. Which relationship makes the neck important during pancreatic resection?

• It surrounds the inferior vena cava
• It is separated from all major vessels by the peritoneal cavity
• It lies within the splenic hilum
• It overlies the portal-superior mesenteric venous axis
