the left renal vein
Several vein locations are __________ to their sister arteries
parallel
Transverse Pancreas is _________
Long axis
Sagittal pancreas is _________ axis
Short axis
Pancreatic tail is ___________ and slightly ____________ to spleen
Posterior and slightly superior
What artery is always more anterior than common bile duct?
Gastroduodenal artery
Primary duct of pancreas
Duct of Wirsung
What is measured anteroposterior of the pancreas ?
Head, neck, body, and tail
Pancreatic neck location
Between the pancreatic head and body
Anterior to sma
Anterior to portal splenic confluence
Pancreatic body location
Anterior to aorta
Superior to sma and splenic vein
Largest portion of the pancreas
Pancreatic body
Splenic vein location
Runs along the posterior superior surface of the body and tail, closely following the shape of the gland
Runs along posterosuperior surface
Where is the pancreas bordered?
Right laterally by the neck
Left laterally by the tail
Anteriorly by the posterior wall of the stomach
What part partially surrounds the head of the pancreas?
The C-loop of duodenum
Uncinate process definition
Posteromedial projection of the pancreas head
Location of uncinate process
Lies directly posterior to the SMA and directly anterior to the inferior vena cava or in some cases, due to its size, the aorta.
How to visualize the uncinate process
Draw an imaginary line from the middle of the portal splenic confluence to the middle of the IVC on a transverse image of the mid epigastrium.
The tissue located to the right of the imaginary line is most likely the uncinate process.
Pancreatic tail location
Lies left lateral to the pancreas body and aorta and extends to the hilum of the spleen.
Situated between the stomach anterjorly and left kidney posteriorly
The tail may lie higher, lower, or even on an even level with the body.
The arterial supply of the pancreas includes blood from the….
Pancreaticoduodenal arteries and beaches of the splenic artery
Pancreaticduodenal arteries
Branches of the gastroduodenal artery and SMA
What branches of the splenic artery supply the body and tail of the pancreas with blood?
Pancreatic branches
Splenic artery location
Runs along the superior edge of the pancreas body and tail parallel to the splenic vein
The splenic artery is normally ____________ and can course anteriorly to the lateral portion of the tail
Tortuous
The splenic artery consists of four sections, list them.
Supra pancreatic
Pancreatic
Pre pancreatic
Prehilar
Suprapancreatic
The first 3 cm of the splenic artery as it originates from the celiac axis
The dorsal pancreatic artery originated from this section
Pancreatic section
within the pancreas.
The pancreatic magna, or great artery, originates from this section.
Prepancreatic
Before it leaves the pancreas.
The caudal pancreatic artery originated from the prepancreatic or prehilar sections
Prehilar
Before it enters the spleen.

What type of exocrine and endocrine gland is the pancreas
Digestive exocrine, and a hormonal endocrine
What percent of the pancreatic gland is exocrine?
90%
What percent of the pancreatic gland is endocrine?
10%
What percent of the pancreatic gland is composed of endocrine tissue?
2%
The exocrine function/ducts is carried out by what type of cells of the pancreas
Acini cells
