The Anterior Cerebral Artery (ACA) is a major blood vessel that supplies oxygenated blood to the frontal and parietal lobes of the brain. It branches off from the Internal Carotid Artery and runs along the medial surface of the cerebral hemispheres. The ACA is crucial for functions such as movement, reasoning, and emotional regulation. In addition to supplying blood, the ACA is involved in various neurological conditions. Blockage or rupture of the ACA can lead to anterior cerebral artery syndrome, which may result in weakness, sensory loss, and cognitive impairments. Understanding the ACA's role is essential for diagnosing and treating related brain disorders.
