Maximizing acetylcholine release from synaptic vesicles at neuromuscular junctions
B)
Preventing demyelination of the efferent cerebellar pathways
C)
Increasing the functional ability of the underactive dopaminergic system
D)
Preventing axonal degradation of motor neurons
Ans:
C
Feedback:
Antiparkinson drugs act by increasing the functional ability of the underactive dopaminergic system. The cerebellar pathways, acetylcholine levels, and axonal degradation are not components of the etiology of Parkinson disease.
