Which of the following artery does not supply medulla?
Ans. d. Superior cerebellar artery (Ref BDC 4/e vol-III/202-203)Medulla is supplied by anterior spinal artery, branches of vertebral artery and posterior inferior cerebellar artery (but not the Superior cerebellar artery).Blood supply of Medulla Oblongata1. Anterior spinal arteryQ:The anterior spinal artery supplies the whole medial part 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 artery' (PICA)g:The posterior inferior cerebellar artery', a major branch of the vertebral artery, supplies the posterolateral part of the medulla, where the main sensory tracts run and synapse.3. Direct branches of the vertebral artery0:The vertebral artery supplies an area between the other two main arteries, including the nucleus solitarius and other sensory nuclei and fibersLateral medullary syndrome can be caused by occlusion of either the PICA or the vertebral arteries.
