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
The cerebellum is crucial for the coordination of movement. It receives signals from the motor cortex about the intended movement and the actual position of the limb through climbing fibers. By timing these signals, it helps to stop the movement at the correct point by inhibiting the agonist muscles and stimulating the antagonist muscles.
