Abdomen 3 Flashcards
the small and large intestine are supplied by what
the superior and inferior mesenteric aa.
the superior mesenteric a. supplies what region
mid duodenum through to the mid-transverse colon
the superior mesenteric arises at what vertebral level
L1
the superior mesenteric a. emerges from behind what organ?
from behind the head of the pancreas at the uncinate process and horizontal (3rd part) of the duodenum
The superior mesenteric a. extends down where
extends in the root of the mesentery toward the terminal portion of the ileum
first branch of the superior mesenteric a.
inferior pancreatico-duodenal a.
what does the inferior pancreatic-duodenal a. anastomose with
the superior pancreatic-duodenal a. off the common hepatic branch of the celiac trunk
Off to the left side of the superior mesenteric artery arise what branches
jejunal and ileal branches (intestinal arteries)
what is the second major branch of the superior mesentaric a. and what does it supply
middle colic a. that supplies the midtransverse colon
what is the 3rd branch off the superior mesenteric a.
right colic a. that passes towards the ascending colon
what is the 4th branch off the superior mesenteric a.
ileocolic a. that extends toward the cecum
which artery ends up anastomosing with the terminal portion of the superior mesenteric?
ileocolic a., together they form an anastomotic loop
the anastomotic loop of the superior mesenteric terminal branch and the ileocolic a. gives off what
anterior and posterior cecal aa.
the posterior cecal aa. gives rise to what artery?
appendicular a.
the inferior mesenteric a. supplies what region
the hind gut, remainder of the transverse colon
what is the first branch off the inferior mesenteric a. and what does it supply
left colic a. that goes up to anastomose with the marginal artery to supply the last part of the transverse colon
what branches off the left colic artery?
the descending branch that supplies the descending colon
what arteries branch of the inferior mesenteric to supply the sigmoid colon?
sigmoid arteries
what is the final branch of the inferior mesenteric a. and what does it supply
superior rectal a. that supplies the upper rectal area
what arteries supply the remainder of the rectum
middle and inferior rectal arteries
where do the middle rectal arteries arise from
internal iliac artery
where do inferior rectal arteries arise from
internal pudendal arteries
what two arteries contribute to the formation of the marginal artery
sigmoid and left colic aa.
blood from the stomach and intestines is carried to where
to the liver via the hepatic portal system
