Speed of Nerve Impulses - The Physics Factbook

These signals travel from the brain to the spinal cord, through the nerves to the organs, tissues and muscles. The speed of a nerve impulse varies with the type of nerve impulse the nervous system is sending. Some signals such as those for muscle position, travel at speeds up to 119m/s. Nerve impulses such as pain signals travel slower at 0.61m/s.
