Major duodenal papilla

On the left the opened duodenum with a view of the major duodenal papilla . From above, next to the portal vein (vena portae), the ductus choledochus (referred to as the commons bile-duct in the picture ) descends behind the duodenum and is visible again shortly before the confluence with the papilla duodeni major (hidden section shown with dashed lines). In the prepared pancreas, the pancreatic duct running from right to left to the papilla duodeni major is clearly visible. The accessory pancreatic duct sometimes opens into a separate papilla (papilla duodeni minor) in the duodenum.

The papilla duodeni major , papilla Vateri or Father's papilla (after Abraham Vater ) is a small elevation with a sphincter muscle above the so-called ampulla Vateri , the common mouth of the main bile duct ( ductus choledochus ) and pancreatic duct ( ductus pancreaticus ) in the duodenum (duodenum). It is located in the posterior (dorsal) descending part (pars descendens) of the duodenum.

Father's papilla

The ring-shaped sphincter muscle consisting of smooth muscles is called the Musculus sphincter Oddii (after Ruggero Oddi ; Syn. Oddi-Sphinkter , Musculus sphincter ampullae hepatopancreaticae ). Due to its state of contraction, it regulates the emptying of the bile from the main bile duct and the secretion of the pancreas from the pancreatic duct into the duodenum.

The addition of the name major comes from the fact that a second, smaller papilla is occasionally formed in humans. This is then referred to as the minor duodenal papilla . In some mammals, the second papilla is formed regularly.
