Intermediate Accessory Pancreatic Duct Quiz

Q1. What embryologic event normally establishes communication between the dorsal and ventral pancreatic duct systems?

• Fusion of the dorsal and ventral pancreatic buds after rotation
• Rotation of the hindgut
• Closure of the vitelline duct
• Fusion of the spleen with the pancreas

Q2. Which portion of the dorsal pancreatic duct may persist as the accessory pancreatic duct after normal fusion?

• Proximal dorsal duct leading to the minor papilla
• Cystic duct
• Entire ventral duct leading to the major papilla
• Common bile duct within the liver

Q3. How does the accessory duct usually relate to the main pancreatic duct in a communicating ductal pattern?

• It communicates with the main duct and courses to the minor papilla
• It joins the portal vein
• It empties into the gallbladder
• It runs from the pancreatic tail to the spleen

Q4. What is pancreas divisum?

• Complete absence of the pancreatic head
• Failure of normal fusion of dorsal and ventral pancreatic ducts
• Congenital absence of the duodenum
• Fusion of the pancreatic and cystic ducts

Q5. In classic pancreas divisum, most pancreatic secretion drains through which route?

• Common bile duct through the major papilla
• Portal vein through the liver
• Dorsal duct through the minor duodenal papilla
• Ventral duct through the gallbladder

Q6. Why is the accessory pancreatic duct considered anatomically variable?

• Its location changes between the abdomen and thorax
• It is always absent in adults
• It always replaces the common bile duct
• Its patency and communication with the main duct vary among individuals

Q7. How does the minor papilla relate to the major papilla in typical anatomy?

• It lies inside the stomach
• It is usually superior and proximal to the major papilla
• It is always distal in the jejunum
• It is located in the ileum

Q8. Which part of the pancreas is derived predominantly from the dorsal pancreatic bud?

• Only the gallbladder
• Only the distal common bile duct
• Most of the pancreas, including body and tail
• Only the uncinate process

Q9. Which pancreatic structures are derived mainly from the ventral pancreatic bud?

• Entire body and tail
• Left hepatic lobe
• Uncinate process and inferior part of the head
• Spleen and pancreatic tail

Q10. Why is the accessory duct clinically relevant during ductal imaging?

• It directly measures portal pressure
• It helps demonstrate pancreatic ductal anatomy and fusion variants
• It determines hepatic venous segmentation
• It identifies the renal collecting system
