Histology and Embyology: Pancreas

Pancreas

PANCREAS

It is an endodermal derivative. The outpocketings from the endodermal lining of the gut are the indications of future pancreas. These buds arise on the opposite sides of duodenum, one on the dorsal side and the other on the ventral side.
The dorsal bud lies in front of the hepatic diverticulum. The ventral bud lies in the angle between the gut and the hepatic diverticulum.
Unequal growth of duodenal wall shifts the bile duct dorsally and the ventral primordium of the pancreas is shifted dorsal and is brought nearer to the dorsal primordium. During futher development two primordia fuse.
By proliferation, the duct system develop into acini, some epithelial buds loose connection with ducts and develop as islets.
