Pancreas Flashcards
Which two vertebral bodies does the pancreas cross
L1 and L2
What lies anterior to the pancreas on the right
the stomach between the duodenum
What lies posterior to the pancreas on the left
Spleen
Parts of the pancreas
Head, Uncinate process, neck, body, and
tail.
Describe location of the head of the pancreas
lies within the C-shaped concavity of the
duodenum.
Describe location of the uncinate process of the pancreas
passes posterior to the superior mesenteric vessels.
Describe location of the neck of the pancreas
anterior to the superior mesenteric
vessels. Posterior to the neck of the pancreas, the superior
mesenteric and splenic veins join to form the portal vein
Describe location of the body of the pancreas
elongate and extends from the neck
to the tail of the pancreas
Describe location of the tail of the pancreas
between layers of the splenorenal
ligament
Two pancreatic ducts
Main pancreatic duct and accessory pancreatic duct
Which sphincters
prevent reflux of digestive secretions and
duodenal content
The sphincter of the pancreatic duct , the
sphincter of the bile duct , and the hepatopancreatic sphincter (of
Oddi)
Which sphincter controls the flow of digestive secretion (bile) into the
duodenum.
the sphincter of the bile duct
Arterial supply of the pancreas
splenic, superior mesenteric and gastroduodenal
artery
Which arteries supply the head of the pancreas
The anterior and posterior superior pancreaticoduodenal
arteries, and the
anterior and posterior inferior pancreaticoduodenal arteries
Venous drainage of the pancreas
occurs via corresponding pancreatic veins,
tributaries of the splenic and superior mesenteric parts of the hepatic portal vein
Lymphatic drainage of the pancreas
Pancreaticosplenic lymph nodes. Some vessels end
in the pyloric lymph nodes. Efferent vessels from these nodes drain to the superior
mesenteric lymph nodes or to the celiac lymph nodes via the hepatic lymph nodes
Nerve supply of the pancreas
e vagus and abdominopelvic
splanchnic nerves
Which nerve fibers are distributed to pancreatic
acinar cells and islets
sympathetic and parasympathetic
Which fibers are secretomtor
Parasympathetic
Parasympathetic fibers rely on which hormone
Secretin and cholecystokinin
Cancer of which part of the pancreas accounts for accounts for most cases of extrahepatic obstruction of the biliary ducts
cancer of the head of the pancreas
Obstruction of what causes jaundice
Biliary tract
