neurotransmitters A range of small-molecule chemical substances released by EXOCYTOSIS from a nerve ending on the arrival of a nerve impulse. Neurotransmitters are specific to particular neurons. They interacts with receptors on adjacent structures to trigger off a response, either excitatory or inhibitory. The adjacent structure may be another nerve, a muscle fibre or a gland. The main neurotransmitters are acetylcholine, glycine, glutamate, dopamine, noradrenaline, adrenaline, serotonin, histamine and GABA (gamma-amino-butyric acid). With the exception of the adrenalines all the neurotransmitters are AMINO ACIDS or derivatives of amino acids.NeurotransmittersChemicals within the nervous system that transmit information from or between nerve cells.Mentioned in: Bulimia Nervosa, Impotence, Pain, Withdrawal Syndromes |
