MICROANATOMY

Detailed explanation-1: -The portion of the ventral duct between the dorsal-ventral fusion and major papilla is termed the duct of Wirsung. The portion of the dorsal duct upstream to the dorsalventral fusion point is called the main pancreatic duct.

Detailed explanation-2: -The main pancreatic duct (also known as the duct of Wirsung 13, 14) runs through the center of the gland from left to right (i.e. toward the duodenum). It drains most of the pancreas (the embryological dorsal bud), except for the uncinate process and inferior aspect of the head.

Detailed explanation-3: -The main pancreatic duct develops from both pancreatic buds. The distal portion of the main duct develops from the ventral bud, and following bud fusion is named the duct of Wirsung. The duct drains into the common bile duct via the major papilla.

Detailed explanation-4: -Abstract. The accessory pancreatic duct (APD) is the main drainage duct of the dorsal pancreatic bud in the embryo, entering the duodenum at the minor duodenal papilla (MIP).
