Caption = Outer surface of cerebral hemisphere, showing areas supplied by cerebral arteries. (Blue is region supplied by anterior cerebral artery.)
Caption2= The arterial circle and arteries of the brain. The anterior cerebral arteries (top of figure) arise from the trifurcations of the internal carotid arteries into the anterior cerebral artery,
middle cerebral arteryand posterior communicating arteryon each side.

human anatomy, each anterior cerebral artery supplies oxygento most medial portions of frontal lobes and superior medial parietallobes. The 2 anterior cerebral arteries arise from the internal carotid arteryand are part of the Circle of Willis.
The left and right anterior cerebral arteries are connected by the
anterior communicating artery.
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
# Approximately 1 inch of the lateral surface of frontal and parietal lobe next to the
medial longitudinal fissure
# Anterior portions of the
basal gangliaand internal capsule
# Olfactory bulb and tract
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
Paralysisof the contralateral footand leg
Sensory lossin the contralateral foot and leg
# Left sided strokes may develop transcortical motor aphasia
# Gait apraxia
Urinary incontinencewhich usually occurs with bilateraldamage in the acute phase
