This graphic shows an example of a synapse of a cholinergic neuron. A cholinergic neuron uses acetylcholine as neurotransmitter. Acetylcholine is synthesized by the choline acetyltransferase enzyme from AcetylCoA and recycled choline. Acetylcholine is then stored in the axon for release. There are 4 different acetylcholine receptors subtypes identified. Nicotinic
