Testicular artery Testicular artery The testicular artery (the male gonadal artery, also called the internal spermatic arteries in older texts) is a branch of the abdominal aorta that supplies blood to the testis. It is a paired artery, with one for each of the testes. It is the male equivalent of the ovarian artery. Because the testis is found in a different location than that of its female equivalent, it has a different course than the ovarian artery. They are two slender vessels of considerable length, and arise from the front of the aorta a little below the renal arteries. Each passes
Trigeminal artery 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 primitive internal carotid artery during development, when the embryo is approximately 6 weeks old. The trigeminal artery then anastomoses with the basilar artery. At this point in development, the trigeminal artery serves as the main blood supply for the hindbrain, as other vessels in the
