Q

functions of stomach

A
  1. reception and storage of food (adult capactiy 2-3 liters)
  2. mechanical and chemical digestion: making chyme with gastric juices and hcl
  3. releasese chyme into the duodenum

25
order of lymph drainage of stomach
celiac nodes > intestinal trunk > cisterna chyli >thoracic duct > l braciocephalic v
26
nerve supply of the stomach
vagus nerve and greater splanchnic
27
vagus n supplies
ps fibers: secretomotor to gastric glands, motor to smooth muscles of stomach, inhibitory fibers: pyloric sphincter
28
splancnic n supplies
motor fibers to pyloric sphincter and blood pain transmitting nerve fibers
29
vagus fibers specifically preg
preg parasymp, gva (vagovago reflex/stretch)
30
splanchnic fibers specifically
pregan symp gva (pain)
31
splanchnic synapses at
celiac ganglion
32
pancreas lies posterior to stomach and extends
from posterior abdominal wall from duodenum to the spleen
33
pancrease is ()peritoneal except for ()
retroperitoneal, tail
34
pancreas is what type of galnd
exocrine and endocrine
35
what does the pancreas secrete exocrine
digestive enzyme, gastric, sodium bicarbonate
36
pancrease secrete endocrine
glucagon, insulin, somatostatin
37
pancreas crosses what vertebrae
L1 and L2
38
head surrounded by ()
duodenum
39
extension of pancreas head
uncinate process
40
what vessels are behind neck of pancreas
portal vein, part of aorta, sup mesenteric a. and v.
41
where anatomically find splenic a and v
splenic a runs superior border of body, posterior v directly posterior
42
main pancreatic duct joins () to make ()
common bile duct, (protrudes to second duodenal to make) major duodenal papilla
43
accesory pancreatic duct makes
minor duodenal papilla
44
2 blood supplies of pancreas head and uncinate process
superior pancreaticoduodenal (branch of gastroduodenal) inferior pancreaticoduodenal (branch of superior mesenteric)
45
blood supplies of pancreas tail
branch of splenic a
46
lymphatic vessels of pancreas follow blood vessels drain into
pancreato-splenic nodes, pyloric nodes
47
efferent lymphatics of pancreas drain into(3)
celiac nodes, hepatic nodes, superior mesenteric nodes
48
pancreas nerve supply
ps: vagus n , secretomotor sp: greater abdominal splancnic, vasomotor celiac ganglia celiac plexus: post sp, pre ps
49
splenectomy
removal of spleen (can prevent internal hemmoraghing from rupture)
50
where does the spleen lies beneath
left hypochondriac region close to 9th, 10th, 11th ribs
51
relations of spleen
anterior: stomach medial: left kidney, tail of pancreas inferior: left colic flexure (splenic flexure: bending of colon) posterolateral: diaphragm, left pleura, left lung, ribs 9-11
52
function of spleen
prenatal hempoisis, and break down platelates, makes lymphocytes
53
autotransmission
contract spleen smooth muscle so blood can come out of resoirvoir
54
ligaments of spleen
gastrosplenic (gastrolineal) and lienorenal (splenorenal)
55
gastrosplenic attaches
spleen to upper part of greater curvature of stoamch
56
lienorenal attaches
hilum of spleen to left kidney
57
blood supply of spleen
splenic a and v
58
nerve supply of spleen
celiac plexus
59
what drains into portal v
left/right gastric v, splenic v, sup mese
60
lymph drainage of spleen
pancreatico-splenic lymph nodes
61
nerve supply of spleen
celiac plexus
62
nerves of spleen are distributed via the branches of the
splenic a
63
pancreatic cancer does what
compresses bile duct, so bile duct backs up to liver and bilirubin so get post hepatic jaundice
64
splenomegaly due to
leukemia, lymphoma, infections
65
what could happen if have splenectomy
predispose you to fungal infections/exotic infections
66
what drains into portal v
left/right gastric v, splenic v, sup mese
67
lymph drainage of spleen
pancreatico-splenic lymph nodes
68
nerve supply of spleen
celiac plexus
69
nerves of spleen are distributed via the branches of the
splenic a
70
pancreatic cancer does what
compresses bile duct, so bile duct backs up to liver and bilirubin so get post hepatic jaundice
71
splenomegaly due to
leukemia, lymphoma, infections
72
what could happen if have splenectomy
predispose you to fungal infections/exotic infections
