There are three key steps to voluntary movement:
-
Planning movement - cortical association areas, cerebellum and basal nuclei
-
Initiating movement - motor cortex
-
Executing movement - cerebellum, brainstem
- Sensory input is passed from the motor cortex to the motor association centres
- Planning and decision making occurs in the basal nuclei and thalamus
- Coordination and timing requires cerebellar input
- Execution occurs via information being relayed down the corticospinal tract to the skeletal muscles and the extrapyramidal tract has an influence on posture, balance and gait
- The sensory receptors provide continuous feedback
