Nervfibrer som skjuter ut från sympatiska ganglier till synapser på målorgan. Postganglionära sympatiska fibrer producerar neurotransmittorn noradrenalin, förutom de som innerverar merokrina körtlar (och möjligen vissa blodkärl), vilka producerar acetylkolin. De kan även utsöndra neuropeptider.
Nerve fibers which project from sympathetic ganglia to synapses on target organs. Sympathetic postganglionic fibers use norepinephrine as transmitter, except for those innervating eccrine sweat glands (and possibly some blood vessels) which use acetylcholine. They may also release peptide cotransmitters.
