Cerebral cortex
Definition
Decision (choice) to make a voluntary movement
Term
Basal nuclei
Cerebrum
Definition
Initiates actual impulse in neural pathway for muscle contraction
Term
Cerebellum
Definition
Subconscious coordination of voluntary muscle (compares sensory input from eye, inner ear and muscles/joints with the 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)
