- Neurotransmitters are synthetized in and released from nerve endings into the synaptic cleft. From there, neurotransmitters bind to receptor proteins in the cellular membrane of the target tissue. The target tissue gets excited, inhibited, or functionally modified in some other way.

10 - Synthesis, release and fate of neurotransmitters
WEBThe advent of the intracellular microelectrode demonstrated, as we have seen in chapter 7, that the transmission process is dependent in most cases upon the release of a chemical substance, the neurotransmitter, from the presynaptic nerve terminal.
Neurotransmitter - Wikipedia
Neurotransmitters are generally synthesized in neurons and are made up of, or derived from, precursor molecules that are found abundantly in the cell. Classes of neurotransmitters include amino acids, monoamines, and peptides. Monoamines are synthesized by altering a single amino acid. For example, the precursor of serotonin is the amino acid tryptophan. Peptide transmitters, or n…
