Tempkin Ch 16

Pancreas

TermDefinition
duct of wirsung main pancreatic duct. transports and discharges pancreatic juice into the duodenum through the ampulla of vater to aid the digestive process
ampulla of vater dilation in the second portion of the duodenum, where the common bile duct and pancreatic duct(s) enter to discharge substances that aid in the digestive process
duct of santorini pancreatic accessory duct that enters the duodenum approximately 2cm superior to the duct of wirsung
portal splenic confluence area just posterior to the neck of the pancreas, where the splenic vein meets the superior mesenteric vein. together, these veins form the portal vein.
splenic vein along with tributaries of the superior mesenteric vein, serves as the venous drainage for the pancreas
superior mesenteric vein along with tributaries of the splenic vein, serves as venous drainage for the pancreas
portal vein formed by the confluence of the splenic vein and superior mesenteric vein just posterior to the neck of the pancreas
pancreas head lies right lateral to the superior mesenteric vein. cradled in the c-loop of the duodenum, directly anterior to the inferior vena cava
common bile duct (CBD) distal portion of the biliary tract that transports and then discharges bile into the duodenum as needed to aid the digestive pocess
gastroduodental artery first branch of the common hepatic artery. courses along the anterolateral aspect of the pancreas head just right lateral to the pancreas neck, where it divides into anterior and posterior superior pancreaticoduodental branches.
uncinate process posteriomedial projection of the pancreas head that lies directly posterior to the superior mesenteric vein and directly anterior to the inferior vena cava or in some cases, due to its size, the abdominal aorta.
pancreatic neck situated between the pancreatic head and body immediately anterior to the superior mesenteric vein.
pancreatic body bordered right laterally by the pancreas neck, left laterally by the pancreas tail, anteriorly by the posterior wall of the stomach, and posteriorly by the splenic vein. considered the largest portion of the pancreas.
pancreatic tail left lateral to the pancreas body and aorta and extends to the hilum of the spleen, situated between the stomach anteriorly and left kidney posteriorly. the splenic vein runs along its posterosuperior surface.
pancreaticoduodenal arteries arteries that supply the head of the pancreas and part of the duodenum with blood. part of the pancreatic arcades
pancreatic arcades the vascular connection between the pancreaticoduodenal, hepatic, splenic, and superior mesenteric arteries that supply blood to the head of the pancreas
splenic artery supplies the body and tail of the pancread with blood. from its orgin at the celiac axis it runs along the superior edge of the pancreas body and tail parallel to the splenic vein
suprapancreatic splenic artery first 3 cm section of the artery as it originates from the celiac axis
prepancreatic splenic artery section of the artery before it leaves the pancreas
pancreatic splenic artery section of the artery located within the pancreas
prehilar spenic artery section of the artery before it enters the hilum of the spleen
exocrine produces and transports pancreatic juice via ducts to aid in digestion
endocine produces and secretes hormones directly into the bloodstream with a ductal system
acini cells produce pancreatic juice that is composed of enzymes to help digest fats, proteins, carbohydrates and nucleic acids
pancreatic juice composed of enzymes produced by acini cells in the pancreas that help digest fats, proteins, carbohydrates and nucleic acids
sphincter of oddi muscle surrounding the ampulla of vater that controls the flow of pancreatic juice from the pancreas and bile from the biliary tract into the duodenum
alpha cells produce pancreatic juice that is composed of enzymes to help digest fats, proteins, carbohydrates and nucleic acid
beta cells constitute 60% to 70% of the pancreatic endocrine cells that produce insulin
delta cells cells that account for approximately 5% of pancreatic endocrine tissue that produces the hormone somatostatin
gamma cells pancreatic polypeptide (Pp) cells that comprise less than 5% of pancreatic endocrine cells and may affect blood sugar regulation
epsilon cells cells that account for less than 1% of pancreatic endocrine cells, and produce the hormone ghrelin, which may affect blood sugar regulation
islets of langerhan groups of alpha, beta, and delta endocrine cells in the pancreas that produce insulin
insulin hormone produced by beta cells in the pancreas that cause glycogen formation from glucose in the liver
glucagon hormone produced by alpha cells in the pancreas that causes the release of glucose to meet the immediate energy needs of the body
somatostatin hormone produced by alpha cells in the pancreas that inhibits the production of insulin and glucose
