(For the Circulus or Circle of Willis, the posterior cerebral artery, and rhe bloodvessels of the cerebellum, see page 617.) The anterior cerebral (a. cerebri anterior) arises from the internal carotid at the inner extremity of the sylvian fissure. It passes forward and inward across the anterior perforated substance, above the optic nerve, to the commence- ment of the intercerebral fissure. Here

(For the Circulus or Circle of Willis, the posterior cerebral artery, and rhe bloodvessels of the cerebellum, see page 617.) The anterior cerebral (a. cerebri anterior) arises from the internal carotid at the inner extremity of the sylvian fissure. It passes forward and inward across the anterior perforated substance, above the optic nerve, to the commence- ment of the intercerebral fissure. Here it comes into close relationship with the anterior cerebral artery of the opposite side, and the two vessels are con- nected by a short anastomosing trunk, about two lines, \ inch (4 mm.) in length, the anterior communicating artery. From this point the two vessels run side by side in the intercerebral fissure, curve around the genu of the corpus callosum, and, turning backward, continue along its upper surface to its posterior part, where they terminate by anastomosing with the posterior cerebral Fig. 449.—Vascular area of the inferior surface of the cerebrum. I. The part supplied by the anterior tem- poral from the posterior cerebral artery. II. The part supplied by the posterior temporal" from the posterior cerebral artery. III. The part supplied by the occipital from the posterior cerebral artery. (After Duret.) Branches.—In their course the anterior cerebral arteries give off the following branches: Antero-median ganglionic. Inferior internal frontal. Anterior internal frontal. Aliddle internal frontal. Posterior internal frontal The antero-median ganglionic are a group of small arteries which arise at the commencement of the anterior cerebral artery; they pierce the anterior perforated.
