Callosomarginal artery-the callosomarginal artery, a branch of the anterior cerebral artery, serves the medial aspect of the superior frontal gyrus and that portion of this gyrus on the superior and lateral aspects of the hemisphere.m4 segments of the middle cerebral artery serve the lateral aspects of the hemisphere; p4 segments of the posterior cerebral artery serve the medial aspects of the hemisphere caudal to the parietoccipital sulcus, and the angular artery (an m4 branch) serves the angular gyrus of the inferior parietal lobule. the lenticulostriate arteries are branches of m1 that serve internal structures of the hemisphere.(p.19,21,25,29,39)
