These secretions are called postganglionic secretions). i) Suppression of Immune system, j) Vasoconstriction and increase in Blood Pressure, k) P u p i l dilation, (Illustration of an excited face with pupils dilated). l) ❋ Adityagawade (2010)

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. ❋ Unknown (1999)

Studies have shown that penile erection is achieved via postganglionic sympathetic adrenergic innervation in concert with parasympathetic neurons. ❋ Ph.D. Richard A. Passwater (1991)

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. ❋ Unknown (1965)

Acetylcholine, injected into the vessels of a ganglion, could be shown to stimulate the ganglion cells to the discharge of postganglionic impulses. ❋ Unknown (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. ❋ Unknown (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. ❋ Unknown (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. ❋ Asimov, Isaac (1963)

In some cases, the ganglia separating the preganglionic fibers from the postganglionic fibers are actually located within the organ the nerve is servicing. ❋ Asimov, Isaac (1963)

The axons of these cell bodies form a second set of fibers, the postganglionic fibers. ❋ Asimov, Isaac (1963)

It is these postganglionic fibers that lead to the visceral organs, usually by way of one spinal nerve or another, since the spinal nerves are "cables" including all varieties of nerve fibers. ❋ Asimov, Isaac (1963)

In that case, the preganglionic fiber runs almost the full length of the total track, whereas the postganglionic fiber is at most just a few millimeters long. ❋ Asimov, Isaac (1963)

The postganglionic fibers, which must travel the remaining way to the organs they are concerned with, are relatively long. ❋ Asimov, Isaac (1963)

This is true also of all the preganglionic nerve endings in the autonomic nervous system, but there is a deviation from this norm in connection with the postganglionic nerve endings. ❋ Asimov, Isaac (1963)

These are preganglionic fibers which end in various sympathetic ganglia from which postganglionic fibers conduct the motor impulses to the smooth muscles of the viscera and vessels and secretory impulses to the glands. ❋ Unknown (1918)

The impulses are distributed from cells in these ganglia through postganglionic fibers to the smooth muscles and glands. ❋ Unknown (1918)

The motor root is supposed to contain sympathetic efferent fibers (preganglionic fibers) from the nucleus of the third nerve in the mid-brain to the ciliary ganglion where they form synapses with neurons whose fibers (postganglionic) pass to the Ciliary muscle and to Sphincter muscle of the pupil. ❋ Unknown (1918)

In the sphenopalatine ganglion they form synapses with neurons whose postganglionic axons, vasodilator and secretory fibers, are distributed with the deep branches of the trigeminal to the mucous membrane of the nose, soft palate, tonsils, uvula, roof of the mouth, upper lip and gums, and to the upper part of the pharynx. ❋ Unknown (1918)

The postganglionic fibers pass to the submaxillary gland, it communicates with the sympathetic by filaments from the sympathetic plexus around the external maxillary artery. ❋ Unknown (1918)
