Which of the following best describes the role of the cerebellum in motor control?
- A.Initiation of voluntary motor commands via the corticospinal tract
- B.Integration of sensory input to coordinate timing and precision of complex movements
- C.Direct modulation of muscle tone through the gamma motor neuron loop
- D.Storage of procedural memory for long-term motor skill acquisition
Show correct answer & step-by-step solution
Correct answer: B — Integration of sensory input to coordinate timing and precision of complex movements
Solution
- The cerebellum receives input from the motor cortex and sensory receptors.
- It compares the intended motor program with the actual sensory feedback.
- It calculates error signals to adjust the timing and force of muscle contractions.
- This ensures smooth and coordinated movement.
- Hence the answer is (B).
