WebMD reports that there are three kinds of nerves: motor nerves, sensory nerves and autonomic nerves. Motor nerves control movement by passing signals from the brain and spinal cords to the muscles. Sensory nerves allow the body to feel. They pass information from the skin and muscles to the brain and spinal cord. Autonomic nerves control the involuntary, or partially involuntary, actions of the body, such as heart beat.
