Acetylcholine is a chemical messenger (i.e., a neurotransmitter) that is used to transmit signals inside the body.
Acetylcholine broken down is due to its hydrolysis, which ends cell signaling between brain synapses.
In conclusion, Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.
