Voluntary Motor Control Functions of the Brain

Question 1

Cerebral cortex

Answer 1

Decision (choice) to make a voluntary movement

Question 2

Basal nuclei (cerebrum)

Answer 2

Initiates actual impulse in neural pathway for muscle contraction

Question 3

Cerebellum

Answer 3

Subconscious coordination of voluntary muscle (compares sensory input from eye, inner ear and muscles/joints with choice from cerebral cortex and outputs subconscious muscle control - subconscious, voluntary functions include posture, muscle tone, maintenance of balance and equilibrium in addition to movement)

Question 4

Red nucleus, substantia nigra (midbrain nuclei)

Answer 4

Refinement of subconscious voluntary movement - esp. for muscle tone and muscle stretch reflex
