The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain. The three main arteries are the:

• Anterior cerebral artery (ACA), which supplies blood to the medial portion of the brain, including the superior parts of the frontal and anterior parietal lobes
• Middle cerebral artery (MCA), which supplies blood to the majority of the lateral portion of the brain, including the temporal and lateral-parietal lobes. It is the largest of the cerebral arteries and is often affected in strokes
• Posterior cerebral artery (PCA), which supplies blood to the posterior portion of the brain, including the occipital lobe, thalamus, and midbrain
