The pericallosal artery which runs above the corpus callosum and the callosomarginal artery which runs in the cingulate sulcus, above the cingulate gyrus.
20+ Anterior Cerebral Arteries Anatomy. Origin) of anterior cerebral artery produces contralateral sensorimotor deficits mainly involving the lower extremity with sparing of face and hands (think of the humunculus). The two anterior cerebral arteries arise from the internal carotid artery and are part of the circle of willis.

Variant anatomy of the aca most commonly includes hypoplasia or absence of the a1 segment (10% of individuals). The pericallosal artery which runs above the corpus callosum and the callosomarginal artery which runs in the cingulate sulcus, above the cingulate gyrus. The anterior cerebral artery (aca) along with the middle cerebral artery (mca) forms at the termination of the internal carotid artery (ica).
The anterior cerebral artery is one of the major arteries of the brain.
The anterior cerebral artery (aca) is one of a pair of arteries on the brain that supplies oxygenated blood to most midline portions of the frontal lobes and superior medial parietal lobes. The internal carotid arteries, the anterior cerebral arteries, and the posterior cerebral arteries anastomose through the anterior and posterior communicating arteries to form the circle of willis, a vascular circuit surrounding the optic chiasm and pituitary stalk. Phylogenetically, it is among the oldest vessels in the telencephalic species. The anterior cerebral artery is one of the major arteries of the brain.
