External iliac artery
The arteria iliaca externa (external pelvic artery) arises in humans on each side of the body from the division of the arteria iliaca commonis as an indirect continuation of the abdominal part of the aorta , in most other mammals it is a direct aortic branch.
It lies in front of the iliac blades of the pelvis in front of the iliopsoas muscle . It lies in the groove between its two parts, the psoas major muscle and the iliacus muscle .
In humans, the artery gives off two branches in the pelvic area, the deep circumflex artery and the inferior epigastric artery . The deep circumflex artery gives off an ascending ramus that anastomoses with the iliac ramus of the iliolumbar artery . The inferior epigastric artery sends - in addition to the cremaster artery in men and the arteria ligamenti teretis uteri in women - a ramus pubicus , which then gives off a ramus obturatorius in its further course (see corona mortis ). In the further course, the external iliac artery passes under the inguinal ligament in order to supply the leg with blood as the femoral artery (thigh artery) .
In ungulates, too, the arteria iliaca externa originates from the arteria circumflexa ilium profunda to supply the lateral abdominal wall. In horses, the arteria iliaca externa also originates from the arteria uterina , the main vessel for supplying the uterus .
