Quick Facts

The callosomarginal artery is one of the two terminal branches of the anterior cerebral artery, the other being the pericallosal artery. It commences near the genu of the corpus callosum and then travels along, or near to, the cingulate sulcus. Its path parallels that of the pericallosal artery.

Along its course, the callosomarginal artery gives off anteromedial frontal, intermediomedial frontal, posteromedial frontal, cingular and paracentral branches.

Overall, the callosomarginal artery and its branches provide an arterial supply to the anteromedial and anterosuperior parts of the cerebral hemisphere.
