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.

Anterior Cerebral Artery
The A2 segment of the anterior cerebral artery is the vertical or postcommunicating segment that turns sharply superiorly within the interhemispheric fissure and courses anterior to the rostrum of the corpus callosum, with an anatomically defined transition to the A3 segment at the genu of the corpus callosum.
