minor duodenal papilla

The other names of minor duodenal papilla is Santorini's minor caruncle.

The minor duodenal papilla is the opening of the accessory pancreatic duct into the descending second section of the duodenum.

This part of the duodenum also contains the minor duodenal papilla, the entrance for the accessory pancreatic duct (of Santorini).

However, some have an additional accessory pancreatic duct also called the Duct of Santorini, which connects straight to the duodenum at the minor duodenal papilla.
