A nerve impulse moving along a neuron is an electrical message and across a synapse is a chemical message. At the pre synaptic membrane the chemical messenger (called a neurotransmitter) is released and diffused across the synaptic gap. This message is detected by receptors on the post synaptic membrane. These receptors cause a change in the post synaptic membrane, causing the impulse to continue moving along the next neuron.
