neurotransmission

Explanation:

When the nerve impulses are transmitted from one neuron to another or from one neuron to a muscle, then such a type of signalling is known as neurotransmission. When neurotransmission occurs between two nerves, then the neurons communicate by release a neurotransmitter into the synapse between the two neurons. The neurotransmitters are released by the axon terminals from the presynaptic neuron and they bind onto the dendrites of the postsynaptic neurons. Therefore, in the given example the release of acetylcholine (neurotransmitter) from the preganglionic nerve cell onto the postganglionic nerve cell is an example of neurotransmission.
