Place the following steps in order for motor control. 1. Upper motor neurons stimulate lower motor neurons. 2. Sensory information is relayed back to the cerebellum so movement can be modified if needed. 3. Upper motor neurons in the premotor cortex select a motor program. 4. Lower motor neurons stimulate a skeletal muscle to contract. 5. The basal nuclei enable the thalamus to stimulate upper motor neurons of the primary cortex. |
