Posterior: without peritoneum and in contact with ff.
SMV, left suprarenal gland, aorta and left kidney

27
Q

Posterior part of body of pancreas in contact with?

A

SMV, left suprarenal gland, aorta and left kidney

28
Q

Part of pancreas that is relatively mobile

A

tail

29
Q

Pancreatic arterial supply

A

Pancreatic arteries+splenic arteries = arcades with pancreatic gastroduodenal atery and SMA

30
Q

Arterial supply of head of pacreas

A

Ant and post pancreaticoduodenal arteries

31
Q

T/F duodenum and the head of pancreas share for the most part the same vessels

A

True. This is why duodenum must be removed whent he head of the pancreas is resected.

32
Q

Common blood supply of the head is through the?

A

Two arcades that lie in the anterior and posterior surface of the head of the pancreas

33
Q

Arterial supply of the body and tail?

A

10 splenic artery branches

Dorsal, inferior, great pancreatic arteries

34
Q

Venous drainage of the pancreas

A

pancreatic veins

mostly empty into splenic veins (joins)-> SMV and forms-> hepatic portal vein

35
Q

Lymphatic system of pancreas

A

most terminate at the pancreaticosplenic LN
some: pyloric LN
Drain into SM LN or celiac LN via hepatic LN

Q

Innervation of pancreas

A

from CNX and abdominopelvic splanchnic nerves

para and sympathetic fibers: fromc eliac plexus and SM plexus

37
Q

Parasympathetic fiber fo pancreas

A

secretomotor but pancreatic secretion is primarily mediated by secretin and cholecystokinin

38
Q

pancreatic secretion is primarily mediated by

A

secretin and cholecystokinin

Duct of Santorini (sometimes larger than main pancreatic duct)

42
Q

Duct of Santorini drains what

A

anterosuperior part of head

43
Q

Carcinoma in the head of pancreas causes

A

painless progressive jaundice and distention of GB
