Preferred Label : preganglionic autonomic fiber;
Uberon definition : Nerve fibers which project from the central nervous system to autonomic ganglia. In
the sympathetic division most preganglionic fibers 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 fibers originate in neurons of the brain stem
and sacral spinal cord. In both divisions the principal transmitter is acetylcholine
but peptide cotransmitters may also be released.;
