Medulla oblongata is supplied by the following aeries, except
Blood to the medulla is supplied by a number of aeries:Anterior spinal aery: This supplies the whole medial pa of the medulla oblongata.Posterior Spinal aeryPosterior inferior cerebellar aery: This is a major branch of the veebral aery, and supplies the posterolateral pa of the medulla, where the main sensory tracts run and synapse. It also supplies pa of the cerebellum.Direct branches of the veebral aery: The veebral aery supplies an area between the other two main aeries, including the solitary nucleus and other sensory nuclei and fibers.Basilar aery(Ref: Vishram Singh textbook of clinical neuroanatomy, second edition pg-77)
