Pancreas Anatomy Flashcards
what are the pacreatic buds. what do they turn into?
Ventral - smaller - duct of Wirsung. Main duct <2mm
Dorsal - lgr - duct of santorini. secondary or accessory duct
What do find in the pancreas parenchyma?
Acini cells (provide exocrine function)
isles of langerhauns (provide endocrine functions)
What does the pancreas lie anterior to?
lumbar vertebrae #1 and 2
what plane is the pancreas in?
deep epigastirium and lt hypochondrium
what are the pancreas posterior landmarks?
IVC and Aorta
how does the pancreas sit?
extens horizontally/oblique
2nd part of duodenum to splenic hilum
its head is inferior to its tail
where is the pancreas head in relationship to the duodenum?
Where is it’s tail?
2nd portion of duodenum (2nd/3rd parts are retroperitoneal). head sits in c-loop
tail is superior and posterior to head
in relation to the PV confluence, AO, SMV, SV or AO
where is the head of the pancreas?
where is the uncinate portion of the head of the pancreas?
where is the neck of the pancreas?
where is the body?
tail?
lat to PV confluence and ant to IVC
posterior to the PV Confluence/SMV
ant to PV confluence
ant to SV
side of AO laterally
what is the duct of wirsung?
Major papilla – opening where bile and pancreatic juice flow into duodenum
•
Ampulla of Vater – Area where PD and DCBD join
•
Sphincter of Oddi – The Sphincter of Oddi is a muscular valve that controls the flow of digestive juices (bile and pancreatic juice) through the ampulla of Vater
Duct of Santorini
Minor Papilla
–
Drains into duodenum
what size is the head, neck, body and tail of the pancreas in AP?
head 2-3 cm
neck 1.5-2.5 cm
body 2-2.5 cm
tail 1-2 cm
*all measurements taken perpendicular to panc
what bud does the duct of wirsung arise from?
ventral bud
what bud does the duct of santorini arise from?
the larger bud
what portion of the duodenum is the c-loop in?
2nd
the pancreatic head is typically more __ than its tail?
anterior
what is the lgst part of the pancreas?
head
what is the area where the bile and pancreatic ducts meet?
ampulla of vater
wher is the c-loop of the dodenum?
retroperitoneal
whre are the hepatic and splenic arteries?
peritoneal. aorta is retroperitoneal, but not these branches.
what feeds the pancreas?
what drains it?
Splenic Artery: feeds body, tail
GDA: branch superior Pancreaticoduodenal branches: feeds head and neck
SMA: branch inferior Pancreaticoduodenal: feeds head
Splenic Vein and SMV tributaries
what are the vascular landmarks of the pancreas
CA, CHA, SA form the superior border
what vascular landmarks can you see here?
GDA: Anterior / Lateral border of head
where is the SMA?
posterior to the pancreatic body
where is the PV confluence?
posterior to the neck of the pancreas
