External iliac artery External iliac artery 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 muscles. They exit the pelvic girdle posterior and inferior to the inguinal ligament about one third 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.
Suprascapular artery running between the scapula and the supraspinatus muscle, to which it supplies branches. It then descends behind the neck of the scapula, through the great scapular notch and under cover of the inferior transverse ligament, to reach the infraspinatous fossa, where it supplies infraspinatus and anastomoses with the scapular circumflex artery and the descending branch (aka dorsal scapular artery) of the transverse cervical artery. Besides distributing branches to the sternocleidomastoid (which, however, mainly is supplied by the occipital artery and the superior thyroid artery), subclavius (which mainly is supplied by the thoracoacromial artery), and neighboring muscles, it gives off a
