<span>Nerve cells send electrical impulses along the axon. When these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.
</span>The axon is part of the neuron (nerve cell that carries messages), as well as dendrite. Axons pass the nerve impulses on to other cells, while dendrite <span>receive nerve impulses from other cells. </span><span>The place where the axon of one neuron meets the </span>dendrite<span> of another is called a </span>synapse.
