At the base of the brain, the carotid and vertebrobasilar arteries form a circle of communicating arteries known as the Circle of Willis. From this circle, other arteriesâthe anterior cerebral artery (ACA), the middle cerebral artery (MCA), the posterior cerebral artery (PCA)âarise and travel to all parts of the brain.ormal function of the brainâs control centers is dependent upon adequate supply of oxygen and nutrients through a dense network of blood vessels.
