Neurotransmitter(Shinkei Denta Tsutsutsu,British: Neurotransmitters) IsSynapseIt is a substance that mediates information transmission. Presynaptic cells have a neurotransmitter synthesis system, and postsynaptic cells have neurotransmitters.ReceptorThere is. Neurotransmitters are inactivated after release. Zinc ions that affect postsynaptic cellsNitric oxideIs a neurotransmitter in a broad sense.hormoneIs also an intercellular transmitterAperture releaseAnd binds to the receptor.

Neurotransmitters can be broadly classified into the following three types.
- amino acid(Glutamic acid,γ-aminobutyric acid,Aspartic acid,glycineSuch)
- peptideKind (Vasopressin,Somatostatin,Such)
- MonoamineKind (Noradrenaline,Dopamine,Serotonin)Whenacetylcholine
- acetylcholine (ACh)
