In human anatomy, the anterior cerebral artery supplies oxygen to most medial portions of frontal lobes and superior medial parietal lobes. It arises from the internal carotid artery and is part of the Circle of Willis.

The left and right anterior cerebral arteries are connected by the anterior communicating artery.

Areas supplied

Areas supplied by the anterior cerebral artery include:

1. The medial surface of the frontal and parietal lobes
2. The anterior four- fifths of the corpus callosum
3. Approximately 1 inch of the frontal and parietal cortex
4. Anterior portions of the basal ganglia and internal capsule

Occlusion

Occlusion of the anterior cerebral artery may result in the following defects:

1. Paralysis of the contralateral foot and leg
2. Sensory loss in the contralateral foot and leg
3. Urinary incontinence which usually occurs with bilateral damage

Branches

The anterior cerebral artery branches into e.g. the following arteries:

• Ophthalmic artery
