Intermediate Main Pancreatic Duct Quiz

Q1. How does the main pancreatic duct usually relate to the long axis of the pancreas?

• It lies entirely outside the pancreas
• It crosses only the uncinate process
• It circles the spleen
• It runs longitudinally through the gland

Q2. Which embryonic ductal components usually contribute to the main pancreatic duct?

• Vitelline duct plus urachus
• Proximal dorsal duct only
• Common bile duct plus cystic duct
• Ventral duct plus distal dorsal duct

Q3. What usually becomes of the proximal portion of the dorsal pancreatic duct after normal fusion?

• It forms the splenic artery
• It becomes the common hepatic duct
• It becomes the portal vein
• It may persist as the accessory pancreatic duct

Q4. What is the usual relationship between the main pancreatic duct and accessory pancreatic duct?

• They may communicate within the pancreatic head
• They are venous tributaries
• They always remain completely separate
• They join in the liver

Q5. Which sphincteric complex regulates flow at the terminal pancreaticobiliary region?

• Pyloric sphincter
• Internal anal sphincter
• Sphincter of Oddi
• Upper esophageal sphincter

Q6. Why can obstruction near the major duodenal papilla affect both bile and pancreatic flow?

• Their terminal pathways are closely associated at the major papilla
• The pancreatic duct passes through the gallbladder
• Both drain through the minor papilla exclusively
• The bile duct drains into the pancreatic tail

Q7. What is pancreas divisum?

• Fusion of the pancreas with the spleen
• Complete absence of the pancreas
• Congenital closure of the common bile duct only
• Failure of dorsal and ventral pancreatic duct fusion

Q8. In classic pancreas divisum, which duct drains most pancreatic tissue?

• Ventral duct through the major papilla
• Dorsal pancreatic duct
• Common hepatic duct
• Cystic duct

Q9. Which imaging feature helps trace the main pancreatic duct anatomically?

• Its location inside the splenic vein
• Its longitudinal course through the pancreas
• Its course within the falciform ligament
• Its passage through the renal pelvis

Q10. Why does the main pancreatic duct enlarge progressively toward the head under normal anatomy?

• It receives hepatic veins
• It receives progressively more pancreatic tributaries
• It becomes the portal vein
• It fills with bile from the gallbladder along its entire course
