Tuesday, August 23, 2011

The basilar artery arises from junction of right and left vertebral arteries, supplying oxygenated blood to a part of the brain. Giving off the pontine branches, the basilar artery runs up the in the sulcus basilaris, inferior to the pons, dividing into the posterior cerebral arteries and the superior cerebellar artery just inferior to the pituitary stalk. The basilar artery supply the occipital lobe, the lower margin of the temporal lobe, the cerebellum, internal ear, and brainstem.
