Nerves impulses
WebNerve impulses travel much faster in nerves with a myelin sheath than in those without one. Cranial nerves and spinal nerves . Nerves that directly connect the brain and the … WebThese 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.
