External iliac artery

The external iliac artery ( external iliac artery ) is formed in humans on each side of the body from the division of the common iliac artery as an indirect part of the continuation of the abdominal aorta, most other mammals, it is a direct Aortenast.

It is located in front of the iliac wings of the pelvis in front of the iliopsoas muscle. It lies in the groove between the two units, the psoas major and iliacus musculus.

The artery is in humans in the pelvic area two branches from the profunda artery circumflex iliac and the inferior epigastric artery. The circumflex artery ilium profunda gives off a ramus, which anastomoses with the ramus iliacus artery iliolumbalis. The inferior epigastric artery sends - in addition to the cremasteric artery in the man or the artery of the ligamentum teretis uteri in women - a pubic ramus, which then in its further course to add a ramus obturator (see corona mortis ). In the course of the external iliac artery passes below the inguinal ligament to supply the femoral artery ( femoral artery ) the leg with blood.

Even with the ungulates of the external iliac artery arises from the circumflex artery ilium profunda to supply the lateral abdominal wall. In horses, the external iliac artery arises additionally the uterine artery, the main blood vessel supplying the uterus.
