The process by which a neuronal cell maintains the organization and the arrangement of proteins at the active zone to ensure the fusion and dock of vesicles and the release of neurotransmitters. Any process that modulates levels of neurotransmitter. The process whereby a signal is secreted or discharged into the extracellular medium from a cellular source. The directed movement of a neurotransmitter into, out of, within or between cells by means of some external agent such as a transporter or pore. Neurotransmitters are any chemical substance that is capable of transmitting (or inhibiting the transmission of) a nerve impulse from a neuron to another cell. The controlled release of a substance by a cell. The regulated release of neurotransmitter into the synaptic cleft. A neurotransmitter is any of a group of substances that are released on excitation from the axon terminal of a presynaptic neuron of the central or peripheral nervous system and travel across the synaptic cleft to either excite or inhibit the target cell. Among the many substances that have the properties of a neurotransmitter are acetylcholine, noradrenaline, adrenaline, dopamine, glycine, gamma-aminobutyrate, glutamic acid, substance P, enkephalins, endorphins and serotonin.
