Neurons are the cells that carry messages between parts of the body
... Neurons are separated by narrow gaps called synapses. When the action potential reaches the end of the axon it must pass to the next neuron. The neuron before the synapse (pre-synaptic neuron) releases chemicals called neurotransmitters in response to the action potential. ...
