Pancreatic bud
Encyclopedia
The ventral and dorsal pancreatic buds (or pancreatic diverticula) are outgrowths of the duodenum
during human embryogenesis
. They join together to form the adult pancreas
.
The dorsal pancreatic bud gives rise to the accessory pancreatic duct
, while the ventral pancreatic bud gives rise to the major pancreatic duct
.
In pancreas divisum
, the buds fail to fuse.
Duodenum
The duodenum is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms anterior intestine or proximal intestine may be used instead of duodenum...

Accessory pancreatic duct
Most people have just one pancreatic duct. 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...

Pancreatic duct
The pancreatic duct, or duct of Wirsung , is a duct joining the pancreas to the common bile duct to supply pancreatic juices which aid in digestion provided by the "exocrine pancreas"...

Pancreas divisum
Pancreas or Pancreatic divisum is a congenital anomaly in the anatomy of the ducts of the pancreas in which a single pancreatic duct is not formed, but rather remains as two distinct dorsal and ventral ducts.-Causes:...
