anatomy Flashcards
branches of coeliac trunk
common hepatic artery
left gastric artery
splenic artery
what veins come togethe to form hepatic portal vein
splenic vein
supeiror mesenteric vein
inferior mesenteric vein
what arteries branch from the superior mesenteric
right colic
middle colic
ileocolic
what arteries branches from the infeior mesenteric
left colic
sigmoid
what does the pyloric antrum of stomach contain
pyloric sphincter
folds in liver
5:
- right and left trainagular
falciform
coronary
round
what seperates the caudale and quadrate lobes
porta hepatitis
what is the porta hepatitis formed of
hepatic artery
hepatic portal vein
commno bile duct
hepatic artery function
delivers 02 rich blood from heart to liver
hepatic portal vein
delivers nutrient rich venous blood from gi tract and spleen etc
common hepatic function
drains bile from liver into gall bladder
portal triad
hepatic artery hepatic vein and bile duct
when glucose levels are high
hepatocytes convert glucose into gylocgen via glucogenesis
when glucose levels are low
hepatocytes break down glycogen back to glucose via glycogenolisis
where does bile travel from
from center of lobule to portal triad
what does the bile duct seperate into
right and left heaptic ducts
what do the right and left hepatic ducts unite to form
commonn hepatic which leads to the cystic and then to gall bladder
level of coeliac trunk
t12
level of superior mesenteric
l1
level of infeerior mesenteric
l3
two lines down abdomen
midclavicular lines
top right and left regions
hypocjondrium
middle right and light regions
lumbar
lower right and left regions
inguinal
where do the ureters lead from
kidneys
what does the left gastric artery anasatomse with
rught gatsruc
what sperates right and left liver lobes
falciform ligament
what forms the ampulla of vater
pancreatic duct and common bile duct
splenic vein role
drains blood form foregut structures to hepatic portal vein
inferior mesenteric vein role
drains blood form hingut to splenic
supeiror mesenteric role
drains blood from midgut to hepatic portalh
hepatic portal vein role
drains blood from foregut, midgut and hindgut structures to the liver for first pass metabolism
lower bracnhes of abdominal aorta
branches into right and left common iliacs and then external iliacs
where does the abdominal aorta bifurcate
l5
where does the coeliac trunk arise
T12
Marginal artery of Drummond
anastamoses between superior and infeiror mesenteric arteries
where are insulin and glucagon secreted form
endocrine pancreas from islet of langherhans
exocrine pancreas function
Produces digestive juices containing proteases, lipases, nucleases and amylase, which enter the duodenum via the pancreatic duct
trypsinogen
converted into trypsin by an enteropeptidase and this begins a cascade that results in the activation of other enzymes
what unites to form the comon bile duct
cystic duct and comon hepatic
ERCP
Investigation used to study biliary tree and pancreas
kupferr cells
liver macrophages
what is the spleen protected by
ribs 9-11
intraperitoneal organs
liver
spleen
stomach
1st part duodenum
sigmoid and transverse colon
jejenum
ileum
retroperitoneal organs
pancreas
kidney
2-4th part duodenum
rectum
adrenals
ureters
ascending and descending colon
what organs are more mobile
those that are intraperitoneal
where does the lesser sac lie
posterior to stomach
hasselbach triangle
on left is inguinal ligament
top is inferior epigastric artery
right is lateral border of rectus abominis
where does the jaw openng occur T
temperomandibular joint
jaw opening muscle
lateral pterygoif
jaw closing muscles
medial pteryogid , masseter , temporalis
Enteroendocrine cells:
produce hormones that cotrol sevretions and motility
enterocytes
most numerous cells, tall columnar cells with a brush border, the principle absorptive cell
what part of the gut is the descending colon in
hindgut
hindgut organs
sigmoid colon
rectum
descending colon
distal third of transverse colon
what part of gut is thr ascending colon in
midgut
what part of the gut is the appendix and caecum in
midgut
what part of the gut is thr ascending colon in
midgut
