Detailed explanation-1: -Motor neurones are cells in the brain and spinal cord that allow us to move, speak, swallow and breathe by sending commands from the brain to the muscles that carry out these functions. Their nerve fibers are the longest in the body, a single axon can stretch from the base of the spinal cord all the way to the toes.
Detailed explanation-2: -The cerebellum fine tunes motor activity or movement, e.g. the fine movements of fingers as they perform surgery or paint a picture. It helps one maintain posture, sense of balance or equilibrium, by controlling the tone of muscles and the position of limbs.

Detailed explanation-4: -The basal ganglia and motor cortex form a processing loop whereby the basal ganglia enables the proper motor program stored in motor cortex circuits via the direct pathway and inhibits competing motor programs via the indirect pathway.
