anatomy 6 Flashcards
what are the arteries of the abdomen and about what level do they come off
coeliac trunk T12
superior mesenteric arteries L1
renal arteries L2
inferior mesenteric arteries L3
Aorta bifurcates at L4
what are the vessels supplying the foregut
Coeliac trunk. Supplies the oesophagus to the second part of the duodenum.
Coeliac trunk:
Coeliac trunk has three main branches: the common hepatic artery, the splenic artery and the left gastric artery.
The left gastric artery supplies the lesser curvature of the stomach.
Common hepatic artery:
Coming off of this is the right gastric artery which supplies to the right side of the lesser curvature.
Again from the CHA is the right gastroepiploic artery - supplies greater omentum
Splenic artery;
The left gastric epiploic comes off of here and supplies the greater curvature.
Short gastric artery also off here.
what are the branches of the coeliac trunk
splenic artery, common hepatic artery, left gastric artery
what divisions do we get from the splenic artery what they supply
The left gastric epiploic comes off of here and supplies the greater curvature.
Short gastric artery also off here.
what divisions do we get from the common hepatic artery - what they supply
Coming off of this is the right gastric artery which supplies to the right side of the lesser curvature.
Again from the CHA is the right gastroepiploic artery - supplies greater omentum
where does left gastric artery supply
the lesser curvature
what are the blood vessels of the mid gut
Superior mesenteric artery supplies 2nd part duodenum to the endish of the transverse colon.
right coloic, middle colic, jejunal, ileal, ileocolic supply this area
what do each of the right colic, middle colic, jejunal, ileal, ileocolic supply
right colic is the ascending colon, middle colic is the transverse colon, the jejunal arteries is the jejunum, the ileal arteries is the ileum, the ileocolic is the ileum to the cecum area really
whats the difference between the vasa recta in the jejunum to the ileum arteries
in the jejunum they are taller and have shorter arterial arcades.
in the ileum they are shorter and have more and longer arterial arcades
whats the marginal artery
this is an anastomosing artery between all the colic arteries
what are the vessels of the hindgut
the ascending and descending branch of the left colic, the sigmoid arteries and the superior rectal arteries
where do the left colic, sigmoid and superior rectal arteries supply
the two are obvious its in the name.
left colic has an ascending part for the upper of the descending colon.
the descending part is for the lower of the descending colon
where are some varicies of the liver
the caput madusae are over the stomach, there are the oesophageal varies and the anal varices.
what are the nerves of the GIT and what are their levels of origin
greater sphlanchnic T5-T9
lesser splanchnic T10-T11
least splanchnic T12
