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.
Trigeminal artery cerebellum, midbrain, and parts of the temporal and occipital lobes, meaning that anything disrupting blood flow in the internal carotid artery could lead to ischemia in these regions. In addition, persistent trigeminal artery has been associated with vertebrobasilar insufficiency, brainstem ischemia, and carotid cavernous fistulae. Trigeminal artery The trigeminal artery is an artery that supplies the basilar artery with blood during human embryonic development. Normally, the trigeminal artery involutes after the formation of the posterior communicating artery. However, in some cases, the artery persists into adulthood and can cause medical complications, including intracranial aneurysms. The trigeminal artery arises from the
