2 - This triggers the nerve endings of the neuron in the release of chemical messengers called neurotransmitters .
3 - The neurotransmitters diffuse across the gap between two neurons (the synapse ) and bind with receptors on the membrane of the second neuron.
4 - of the second neuron receptors bind only to specific neurotransmitters and the consequent stimulus to release an electrical impulse .
