How does the cerebellum contribute to motor coordination?
1) By timing and comparing the duration of agonist muscle activity and latency of antagonist activity
2) By directly controlling the force of muscle contraction
3 ) By regulating the rate of nerve impulse conduction in motor neurons
4) By initiating voluntary movement
