In human anatomy, each anterior cerebral artery supplies oxygen to most medial portions of frontal lobes and superior medial parietal lobes. The 2 anterior cerebral arteries arise from the internal carotid artery and are 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:Fact|date=February 2007

# The medial surface of the frontal lobe by the medial orbito-frontal artery, and parietal lobes
# The anterior four- fifths of the corpus callosum
# Approximately 1 inch of the lateral surface of frontal and parietal lobe next to the medial longitudinal fissure
# Anterior portions of the basal ganglia and internal capsule
# Olfactory bulb and tract

Occlusion

Occlusion of the anterior cerebral artery may result in the following defects:Fact|date=February 2007

# If stroke occurs prior to the anterior communicating artery it is usually well tolerated secondary to collateral circulation
# Paralysis of the contralateral foot and leg
# Sensory loss in the contralateral foot and leg
# Left sided strokes may develop transcortical motor aphasia
# Gait apraxia
# Urinary incontinence which usually occurs with bilateral damage in the acute phase
