Please order the steps of voluntary movement. 1) Primary motor cortex sends information to alpha motor neurons 2) The prefrontal and parietal cortices decide to initiate movement. 3) Alpha motor neurons initiate muscle contractions. 4) The supplementary motor area (SMA) uses input from the thalamus and basal ganglia to plan a movement.
