The anterior communicating artery (ACoA) is a vital component of the cerebral circulation system. This blood vessel joins the right and left cerebral hemispheres and provides a crucial link between the anterior cerebral arteries. It is also known as the anterior communicating branch, anterior communicating junction, and communicating artery of the brain. Additionally, some scientists may refer to it as the anterior interhemispheric artery or simply the anterior artery. The ACoA is a vital pathway for blood flow throughout the brain, and its function is essential for healthy cognitive function and overall nerve function across the brain and body.
