Introduction

This section of notes gives an overview of how the pancreas develops. At the foregut/midgut junction the septum transversum generates 2 pancreatic buds (dorsal and ventral endoderm) which will fuse to form the pancreas. The dorsal bud arises first and generates most of the pancreas. The ventral bud arises beside the bile duct and forms only part of the head and uncinate process of the pancreas.

Duodenum/Pancreas Rotation

After the stomach the initial portion of the gastrointestinal tract tube is the duodenum which initially lies in the midline within the peritoneal cavity.

This region, along with the attached pancreas, undergoes rotation to become a retroperitoneal structure.

This diagram shows the rotation with spinal cord at the top, vertebral body then dorsal aorta then pertioneal wall and cavity.
