One nerve cell does not actually touch the next.The message has to be carried by chemicals across a gap called the synapse. The branched ends of axons send out chemicals called neurotransmitters when triggered by a nerve impulse. The chemicals stimulate the next-door cell, setting up a new nerve impulse so that the message carries on its way.
