Which of these events results from disruption of a motor system that supplies inhibitory presynaptic inputs to motor neurons

Question

Quizplus · Accepted Answer

Disruption of inhibitory presynaptic inputs to motor neurons usually leads to increased activity and excitation of motor neurons, resulting in spastic paralysis characterized by increased muscle tone and exaggerated reflexes. Uncoordinated, clumsy movements are more likely to result from disruption of cerebellar function, while paraplegia is usually caused by damage to the spinal cord. Suppression of reflex activity is not usually associated with disruption of inhibitory presynaptic inputs to motor neurons.
