External iliac artery
Encyclopedia
The external iliac arteries are two major arteries which bifurcate off the common iliac arteries anterior to the sacroiliac joint
of the pelvis. They proceed anterior and inferior along the medial border of the psoas major muscle
s. They exit the pelvic girdle posterior and inferior to the inguinal ligament
about 1/3rd laterally from the insertion point of the inguinal ligament on the pubic tubercle
at which point they are referred to as the femoral arteries.. The external iliac artery is usually the artery used to attach the renal artery to the recipient of a kidney transplant.
The external iliac artery arises from the bifurcation of the common iliac artery
. It travels inferiorly, anteriorly, and laterally, making its ways to the lower limb:
The abdominal aorta divides to form the "common iliac arteries" in the lower abdomen, and these vessels supply blood to the pelvic organs, gluteral region, and legs. Each common iliac artery descends a short distance and divides into an internal and an external branch. The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and divides into 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 inguinal ligament in the lower part of the abdomen and becomes the femoral artery.
Sacroiliac joint
The sacroiliac joint or SI joint is the joint in the bony pelvis between the sacrum and the ilium of the pelvis, which are joined together by strong ligaments. In humans, the sacrum supports the spine and is supported in turn by an ilium on each side...
