Pancreas Flashcards
How does the pancreas relate to the peritoneum?
Retroperitoneal
What structure is anterior to the pancreas?
Stomach
What structure is to the right of the pancreas?
Duodenum
What structure is lateral to the pancreas?
Spleen
What are the parts of the pancreas?
Head
Uncinate process
Neck
Body
Tail
What is the head of the pancreas?
Widest part of the pancreas
lies within the C-shaped duodenum
What is the uncinate process of the pancreas?
Projection from inferior part of head of pancreas
extends to left side
What structures are posterior to the head of the pancreas?
IVC
Common bile duct
What structures are posterior to the neck of the pancreas?
Superior mesentery artery and vein
What structure is posterior to the body of the pancreas?
Aorta
What is the body of the pancreas?
Central part of the pancreas
What is the tail of the pancreas?
Tip of the pancreas
What is posterior to the tail of the pancreas?
Left kidney
Spleen
What carries exocrine secretions from the pancreas?
Pancreatic duct
Where does the pancreatic duct begin?
Tail of pancreas
Where does the pancreatic duct travel?
Horizontally through the pancreas
leaves head of pancreas
turns inferiorly
What happens to the pancreatic duct?
Joins with common bile duct
What is formed by the common bile duct and pancreatic duct joining together?
Ampulla of vater
How is the passage of pancreatic exocrine secretions into the duodenum controlled?
Sphincter of pancreatic duct
What is the sphincter of pancreatic duct?
Smooth muscle thickening at end of pancreatic duct
How does the sphincter of pancreatic duct control the passage of pancreatic exocrine secretions into the duodenum?
Contracts
to narrow the pancreatic duct
reduce passage of pancreatic exocrine secretions into ampulla of vater and hence duodenum
How is the passage of both bile and pancreatic exocrine secretions into the duodenum controlled?
Sphincter of Oddi
What is the sphincter of Oddi made up of?
Thickening of smooth muscle in ampulla of vater
How does the sphincter of Oddi control the passage of both bile and pancreatic exocrine secretions into the duodenum?
Contracts
to narrow the ampulla of vater
reduces passage of both bile and pancreatic exocrine secretions into the duodenum
