Detailed explanation-1: -The cerebellum is the second largest part of the brain and is seen behind the cerebrum as two flaps. It coordinates muscular activities and maintains the equilibrium of the body.
Detailed explanation-2: -Muscles move on commands from the brain. Single nerve cells in the spinal cord, called motor neurons, are the only way the brain connects to muscles. When a motor neuron inside the spinal cord fires, an impulse goes out from it to the muscles on a long, very thin extension of that single cell called an axon.
