Detailed explanation-1: -Cerebellum. The cerebellum is located at the back of the brain beneath the occipital lobes. It is separated from the cerebrum by the tentorium (fold of dura). The cerebellum fine tunes motor activity or movement, e.g. the fine movements of fingers as they perform surgery or paint a picture.

Detailed explanation-2: -The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body.

Detailed explanation-3: -Neurons carry messages from the brain via the spinal cord. These messages are carried to the muscles which tell the muscle fibre to contract, which makes the muscles move.

Detailed explanation-4: -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.
