Anterior Cerebral Circulation

The anterior cerebral circulation is the blood circulation to the front part of the brain, consisting mainly of the anterior cerebral artery and the anterior communicating artery. It is a branch of the internal carotid artery, and is responsible for providing blood supply to the medial frontal lobe, parietal lobe, and anterior parts of the temporal lobe. It is essential for cognitive abilities, including abstract thinking and working memory. The anterior cerebral circulation begins with the anterior communicating artery, which is a branch of the Internal Carotid Artery. The anterior communications artery serves to connect the right and left anterior cerebral arteries. This branched artery carries blood to the medial surface of the frontal and parietal lobes. The anterior communicating artery also supports the corpus callosum, which is a bundle of nerve fibers that plays a role in transferring information between all four lobes of the brain. The anterior cerebral artery is a branch of the internal carotid artery and carries oxygenated blood to the frontal, parietal, and temporal regions of the brain. It is divided into two segments, the A1 and A2 segments. The A1 segment supplies the medial part of the frontal lobe, whereas the A2 segment supplies the parietal and temporal regions. The anterior cerebral circulation is essential for higher cognitive functions, including abstract thinking and working memory. These functions can be impaired in individuals with disordered anterior cerebral circulation, such as with ischemic stroke.
