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.
Lateral thoracic artery Lateral thoracic artery In human anatomy, the lateral thoracic artery (or external mammary artery) is a blood vessel that supplies oxygenated blood to the lateral structures of the thorax and breast. It originates from the axillary artery and follows the lower border of the Pectoralis minor muscle to the side of the chest, supplies the Serratus anterior muscle and the Pectoralis major muscle, and sends branches across the axilla to the axillary lymph nodes and Subscapularis muscle. It anastomoses with the internal thoracic artery, subscapular, and intercostal arteries, and with the pectoral branch of the thoracoacromial artery. In the female
