Which of the followinu aery does not supply medulla?
Ans. d. Superior cerebellar aeryMedulla is supplied by anterior spinal aery, branches of veebral aery and posterior inferior cerebellar aery (but not the Superior cerebellar aery).Blood supply of Medulla Oblongata1. Anterior spinal aeryQThe anterior spinal aery supplies the whole medial pa of the medulla oblongata.A blockage (such as in a stroke) will injure the pyramidal tract, medial lemniscus, and the hypoglossal nucleus.This causes a syndrome called medial medullary syndrome.2. Posterior inferior cerebellar aery (PICA)Q:The posterior inferior cerebellar aery, a major branch of the veebral aery, supplies the posterolateral pa of the medulla, where the main sensory tracts run and synapse.3. Direct branches of the veebral aeryQ;The veebral aery supplies an area between the other two main aeries, including the nucleus solitarius and other sensory nuclei and fibers.Lateral medullary syndrome can be caused by occlusion of either the PICA or the veebral aeries.
