25
Neck of the pancreas overlies what

26
Body of the pancreas: peritoneum with or without?
Anterior: with peritoneum and forms part of stomach bed Posterior: without peritoneum and in contact with ff. SMV, left suprarenal gland, aorta and left kidney
27
Posterior part of body of pancreas in contact with?
SMV, left suprarenal gland, aorta and left kidney
28
Part of pancreas that is relatively mobile
tail
29
Pancreatic arterial supply
Pancreatic arteries+splenic arteries = arcades with pancreatic gastroduodenal atery and SMA
30
Arterial supply of head of pacreas
Ant and post pancreaticoduodenal arteries
31
T/F duodenum and the head of pancreas share for the most part the same vessels
True. This is why duodenum must be removed whent he head of the pancreas is resected.
32
Common blood supply of the head is through the?
Two arcades that lie in the anterior and posterior surface of the head of the pancreas
33
Arterial supply of the body and tail?
10 splenic artery branches | Dorsal, inferior, great pancreatic arteries
34
Venous drainage of the pancreas
pancreatic veins | mostly empty into splenic veins (joins)-> SMV and forms-> hepatic portal vein
35
Lymphatic system of pancreas
most terminate at the pancreaticosplenic LN some: pyloric LN Drain into SM LN or celiac LN via hepatic LN
36
Innervation of pancreas
from CNX and abdominopelvic splanchnic nerves | para and sympathetic fibers: fromc eliac plexus and SM plexus
37
Parasympathetic fiber fo pancreas
secretomotor but pancreatic secretion is primarily mediated by secretin and cholecystokinin
38
pancreatic secretion is primarily mediated by
secretin and cholecystokinin
39
main pancreatic duct
Duct of Wirsung
40
connects the duct of Wirsung and common bile duct
Ampulla of Vater
41
Minor pancreatic duct
Duct of Santorini (sometimes larger than main pancreatic duct)
42
Duct of Santorini drains what
anterosuperior part of head
43
Carcinoma in the head of pancreas causes
painless progressive jaundice and distention of GB
44
Small Intestine parts
deuodenum jejunum 2/5 proximally ileum 3/5 distally
45
shortest widest and most sessile part of the small intestine
duodenum
46
Does the duodenum have a mesentery?
No.
47
Duodenum has how many parts? Enumerate.
4. Superior, Descending. Horizontal, Ascending
48
Most movable of all parts of the duodenum
1st part/superior, anteriorly covered by peritoneum but bare posteriorly
49
Part of duodenum from neck of gallbladder to the lower border of L3
2nd part/ descending
50
Part of duodenum that crossed by SMV, L3-L4
3rd part or horizontal
51
Part of duodenum that ascends to the upper border of L2
4th part or ascending
52
Ligament attached to the right crus of the diaphragm at the upper border of L2
Ligament of Treitz
53
after a barium meal, the superior part appears as a triangular homogenous shadow knows as
duodenal cap
54
circular folds in the SI
plicae circulares or valves of Keckring
55
Plicae circulares/valves of keckring permanent or not
permanent
56
Arterial supply of SI
1st part: supraduodenal, retroduodenal and duodenal branches from the R gastric, R gastroepiploic and gastroduodenal/pancreaticoduodenal arteries 2-4th: two arterial arcades
57
Venous Drainage SI
superior pancreaticoduodenal vein -> portal vein | inferior vein -> SMV
58
Lymphatics SI
upward: lymph vessels -> pancreaticoduodenal nodes -> gastroduodenal nodes -> celiac nodes downward: lymph vessels -> pancreaticoduodenal nodes -> superior mesenteric nodes
59
Innervation SI
celiac and superior mesenteric plexuses
