Pericallosal artery

The pericallosal artery (Latin: arteria pericallosa) is a branch of the anterior cerebral artery that supplies the callosal and pericallosal regions of the cerebrum.

The pericallosal artery extends posteriorly from the origin of the callosomarginal artery (also a branch of the anterior cerebral artery), runs in the pericallosal sulcus over the superior surface of the corpus callosum to the splenium, where turns inferiorly and terminates in the third ventricle.

The pericallosal artery supplies oxygenated blood to the medial surface of the cerebral hemispheres, callosal and pericallosal regions.
