Anterior cerebral artery

The anterior cerebral artery supplies most of the superior medial parietal lobes and portions of the frontal lobes with blood. Blood supply to the brain is essential to its functionality, and a lack of blood flow to the vital processes of the brain can cause serious harm. If blood flow is blocked in the anterior cerebral arteries, paralysis or sensory deficits may occur. Anterior cerebral arteries supply blood to the frontal lobes' anterior aspects, areas responsible for higher level cognition including judgment and reasoning. Blockages of these arteries can result in cerebral dementia and linguistic confusion. A blockage may also cause apraxia of gait and can influence the movement of the arms. This artery originates at the internal carotid and travels at a right angle with penetrating branches supplying blood to various parts of the brain. This artery supplies blood to the septal area, the corpus callosum, primary somatosensory cortexes for the foot and leg, the frontal lobes' motor planning areas, and the urinary bladder. The anterior cerebral artery is a component of the Circle of Willis, an arterial anastomatic trunk in the brain.
