Neurotransmitter

Introduction: Neurotransmitter

Description of Neurotransmitter

Neurotransmitter: Any specific chemical agent (including acetylcholine, five amines, four amino acids, two purines, and more than 28 peptides) released by a presynaptic cell, on excitation, that crosses the synapse to stimulate or inhibit the postsynaptic cell. More than one may be released at any given synapse. The neurotransmitters released by presynaptic cells may modulate transmitter release from presynaptic cells. Nitric oxide may be a retrograde neurotransmitter, released from postsynaptic cells, to act on presynaptic cells. [neuro- + L. transmitto, to send across]

Neurotransmitter: Endogenous signaling molecules that alter the behavior of neurons or effector cells. Neurotransmitter is used here in its most general sense, including not only messengers that act directly to regulate ion channels, but also those that act through second messenger systems, and those that act at a distance from their site of release. Included are neuromodulators, neuroregulators, neuromediators, and neurohumors, whether or not acting at synapses.

Neurotransmitter: any of a group of substances that are released on excitation from the axon terminal of a presynaptic neuron and travel across the synaptic cleft to either excite or inhibit the target cell; included are neuromodulators, neuroregulators, neuromediators, neurohormones, and neurohumors, whether or not acting at synapses.
