| autonomic fibres, postganglionic | Nerve fibres which project from cell bodies of autonomic ganglia to synapses on target organs. (12 Dec 1998) |
| autonomic fibres, preganglionic | Nerve fibres which project from the central nervous system to autonomic ganglia. In the sympathetic division most preganglionic fibres originate with neurons in the intermediolateral column of the spinal cord, exit via ventral roots from upper thoracic through lower lumbar segments, and project to the paravertebral ganglia; there they either terminate in synapses or continue through the splanchnic nerves to the prevertebral ganglia. In the parasympathetic division the fibres originate in neurons of the brainstem and sacral spinal cord. In both divisions the principal transmitter is acetylcholine but peptide cotransmitters may also be released. (12 Dec 1998) |
| autonomic ganglia | Visceral ganglia. See: autonomic nervous system. (05 Mar 2000) |
