===Storage===

[[File:Neurotransmitters.jpg|thumb|Synaptic vesicles containing neurotransmitters]]
Neurotransmitters are generally stored in [[synaptic vesicles]], clustered close to the [[cell membrane]] at the [[axon terminal]] of the presynaptic neuron. However, some neurotransmitters, like the metabolic gases carbon monoxide and nitric oxide, are synthesized and released immediately following an action potential without ever being stored in vesicles.<ref>{{cite journal | vauthors = Sanders KM, Ward SM | title = Nitric oxide and its role as a non-adrenergic, non-cholinergic inhibitory neurotransmitter in the gastrointestinal tract | journal = British Journal of Pharmacology | volume = 176 | issue = 2 | pages = 212–227 | date = January 2019 | pmid = 30063800 | pmc = 6295421 | doi = 10.1111/bph.14459 }}</ref>
