WebThe basilar artery is a blood vessel at the back of your brain. It supplies oxygen-rich blood to portions of your brain and central nervous system. The basilar is the main artery that carries blood to the back portion of your brain. It forms where the blood vessels that extend through your spinal cord ( vertebral arteries) come together. The basilar artery arises from the union of the two vertebral arteries at the junction between the medulla oblongata and the pons between the abducens nerves (CN VI). The diameter of the basilar artery range from 1.5 to 6.6 mm. It ascends superiorly in the basilar sulcus of the ventral pons and divides at the junction of the midbrain and pons into the posterior cerebral arteries.
