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.
Basilar artery ventral to the pons and divides at the ponto-mesencephalic junction into the paired posterior cerebral arteries close to the pituitary stalk. Its branches can be divided into two groups: A basilar artery stroke classically leads to locked-in syndrome. Basilar artery In human anatomy, the basilar artery is one of the arteries that supplies the brain with oxygen-rich blood. The two vertebral arteries and the basilar artery are sometimes together called the "vertebrobasilar system", which supplies blood to the posterior part of the circle of Willis and joins with blood supplied to the anterior part of the circle of Willis from
