ad·re·ner·gic neu·ro·trans·mit·ter(adrĕ-nĕrjik nūrō-transmit-ĕr)
Neurotransmitter formed in sympathetic postganglionic synapses (e.g., norepinephrine).
a substance (e.g. norepinephrine, acetylcholine, dopamine) that is released from the axon terminal of a presynaptic neuron on excitation, and which travels across the synaptic cleft to either excite or inhibit the target cell.
each neurotransmitter has its own receptor molecule; these show a high degree of structural homology.
