In writing the 1955 review on the "Pharmacology of vascular smooth muscle," I had become very interested in the mechanisms by which sympathetic postganglionic denervation and certain drugs like cocaine markedly potentiate the response of effector organs to epinephrine and norepinephrine, yet markedly reduce the response to the sympathomimetic tyramine.

Studies have shown that penile erection is achieved via postganglionic sympathetic adrenergic innervation in concert with parasympathetic neurons.

Gaddum23 have shown that stimulation of the preganglionic sympathetic fibres in the neck releases Ac.Ch. in the sup.cerv. ganglion, which itself stimulates the ganglion, so that progressive stimulation is set up in the postganglionic fibres.

Otto Loewi - Nobel Lecture 1965

Acetylcholine, injected into the vessels of a ganglion, could be shown to stimulate the ganglion cells to the discharge of postganglionic impulses.

Sir Henry Dale - Nobel Lecture 1965

You will see that we are thus led to the conclusion that nearly all the efferent neurones of the whole peripheral nervous system are cholinergic; only the postganglionic fibres of the true sympathetic system are adrenergic, and not even all of these.

Sir Henry Dale - Nobel Lecture 1965

We must suppose that this sudden rise in concentration of acetylcholine stimulates the ganglion cell to the discharge of a postganglionic impulse, or initiates a propagated wave of excitation along the muscle fibre.

Sir Henry Dale - Nobel Lecture 1965

The parasympathetic nerve fibers, on the contrary, travel to ganglia within the organ they are aiming at; as a result, the preganglionic fibers are quite long and the postganglionic fibers very short.

In some cases, the ganglia separating the preganglionic fibers from the postganglionic fibers are actually located within the organ the nerve is servicing.
