What abdominal regions does the pancreas occupy
Epigastrium
Let hypochondrium
What are the parts of the pancreas
Ucinate process Head Neck Body Tail
What is the head of pancreas
Widest part of the pancreas embraced by the C-shaped curve of the duodenum
Location of head of pancreas
Right of superior mesenteric vessels
Inferior to transtubercular plane
Where do the superior mesenteric vessels cross the pancreas
Posterior surface of the neck
Anterior to the ucinate process
Where does the splenic vein join the SMV to form the hepatic portal vein
Posterior to the neck of the pancreas
Where does the stomach lie in relation to the pancreas

Course of the pancreatic duct
Begins at the tail and runs to the head where it turns inferiorly and joins the common bile duct
What connects acini
Intercalated ducts
What do the intercalated ducts drain into
Intralobular collecting ducts which then drain into the main pancreatic duct
Arterial supply of the pancreas except the head
Coeliac trunk -> splenic -> pancreatic arteries
E.g. Greater pancreatic artery and dorsal pancreatic artery
Arterial supply of the head of pancreas
Coeliac trunk -> common hepatic -> gastroduodenal -> anterior and posterior superior pancreaticoduodenal arteries
Superior mesenteric -> inferior pancreaticoduodenal -> anterior and posterior inferior pancreaticoduodenal arteries
Venous drainage of the pancreas except the head
Pancreatic veins empty into the splenic vein or SMV
Venous drainage of the head of pancreas
Superior and inferior pancreaticoduodenal veins empty into the SMV
What do pancreatic lymphatic vessels empty into
Pancreaticosplenal nodes
Pyloric nodes
What do the pancreaticosplenal and pyloric nodes drain into
