Anterior cerebral artery 2004354 211801356 2008-05-12T04:20:56Z 131.217.6.8 /* Areas supplied */ {{Infobox Artery | Name = Anterior cerebral artery | Latin = arteria cerebri anterior | GraySubject = 146 | GrayPage = 571 | Width = 335 | Image = Gray517.png | Caption = Outer surface of cerebral hemisphere, showing areas supplied by cerebral arteries. (Blue is region supplied by anterior cerebral artery.) | Image2 = Circle of Willis en.svg | Caption2= The [[circle of Willis|arterial circle]] and arteries of the brain. The '''anterior cerebral arteries''' (top of figure) arise from the trifurcations of the [[internal carotid artery|internal carotid arteries]] into the '''anterior cerebral artery''', [[middle cerebral artery]] and [[posterior communicating artery]] on each side. | BranchFrom = [[internal carotid artery]] | BranchTo = | Vein = [[cerebral veins]] | Supplies = [[cerebrum]] | MeshName = Anterior+Cerebral+Artery | MeshNumber = A07.231.114.228.100 }} In [[human anatomy]], each '''anterior cerebral artery''' supplies [[oxygen]] to most medial portions of [[frontal lobe]]s 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|frontal lobe]] by the medial orbito-frontal artery, and [[parietal lobe|parietal]] lobes # The anterior four- fifths of the [[corpus callosum]] # Approximately 1 inch of the frontal and parietal cortex # 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 ==Additional images== {| class=wikitable align=left width=190px |- |[[Image:Cerebral Cortex location.jpg|120x120px]] |Location of cerebral cortex |}[[Image:Arteries_beneath_brain_Gray_closer.jpg|thumb|right|335px|The arteries of the base of the brain.
