Peripheral (outside of the central nervous system) nerves are tubes that are special in their ability to transmit electric impulses along their length and into or away from the central nervous system. Nerves have specialized receptors for different inputs like hot, cold, sharp and vibration. Smaller nerves are grouped into larger rope-like groups that travel up and down the body.
