Dysmetria is seen in lesion of: (A) Basal ganglia, (B) Cerebellum, (C) Pons, (D) Midbrain
Answer is B. Dysmetria or past- pointing is a prompt initiation for a gross corrective action as attempting to touch an object with a finger results in overshooting to one or other side , but the correction overshoots to the other side. And finger oscillates to and fro. This is typically seen in cerebellar disease. Ref:Ganongs Review of medical physiology;23 rd edition ; pg :258
