In human anatomy, the inferior mesenteric artery (IMA) is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal. The regions supplied by the IMA are the descending colon, the sigmoid colon, and part of the rectum.
The internal iliac artery arises at the bifurcation of the common iliac artery, opposite the lumbosacral articulation, and, passing downward to the upper margin of the greater sciatic foramen, divides into two large trunks, an anterior and a posterior. It is posterior to the ureter, [2] anterior to the internal iliac vein, [2] anterior to the ...
The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery." These vessels supply blood to the muscles and skin in the lower abdominal wall. The external iliac artery passes beneath the ...
The colon receives blood from both the superior and inferior mesenteric arteries. The blood supply from these two major arteries overlaps, with abundant collateral circulation via the marginal artery of the colon. However, there are weak points, or "watershed" areas, at the borders of the territory supplied by each of these arteries, such as ...
The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some people, it is known to connect on the portal vein or the superior mesenteric vein. Roughly, the portal venous system corresponds to areas supplied by the celiac trunk, the superior mesenteric artery, and the inferior mesenteric artery.
The arteries that supply the posterior compartment of the thigh arise from the inferior gluteal and the perforating branches of the profunda femoris artery, [5] a major collateral branch of the femoral artery and part of the anterior compartment of thigh. The femoral artery itself crosses the adductor hiatus to enter the posterior compartment ...
4674. FMA. 70248. Anatomical terminology. [edit on Wikidata] The femoral artery is a large artery in the thigh and the main arterial supply to the thigh and leg. The femoral artery gives off the deep femoral artery and descends along the anteromedial part of the thigh in the femoral triangle.
Intestinal arteries. Loop of small intestine showing distribution of intestinal arteries. The superior mesenteric artery and its branches. The intestinal arteries arise from the convex side of the superior mesenteric artery. They are usually from twelve to fifteen in number, and are distributed to the jejunum and ileum.
