bulbar paralysis

originates from the medulla oblongata. The pyramidal and extrapyramidal tracts pass from the midbrain through the medulla and are susceptible to damage by agents that operate in the area. Paralysis of this type has the characteristics of an upper motor lesion with muscle tone and local tendon reflexes retained.
