Development of Pancreas

Pancreatic Buds

  • Two buds: ventral and dorsal
  • Ventral Pancreatic Bud:
    • Develops with the common hepatic bud (for liver and bile duct)
  • Dorsal Pancreatic Bud:
    • Develops directly from the duodenum

Fusion and Rotation

  • Following rotation, the ventral pancreatic bud rotates and fuses with the dorsal pancreatic bud
  • Forms the uncinate process of the pancreas
  • Ducts anastomose:
    • Duct of the ventral bud -> main pancreatic duct
    • Duct of the dorsal bud -> accessory pancreatic duct
  • Bile duct opens into the main pancreatic duct -> major duodenal papilla

Congenital Anomalies

  • Annular Pancreas:
    • Pancreas forms a ring around the second part of the duodenum
  • Ectopic Pancreatic Tissue:
    • Can be present in the duodenum, stomach wall, small intestine, and Meckel's diverticulum

This is a summary of the development of the pancreas.
