| 释义 | postganglionic adjective medical specializeduk /ˌpəʊst.ɡæŋ.ɡliˈɒn.ɪk/ us /ˌpoʊst.ɡæŋ.ɡliˈɑːn.ɪk/ relating to the nerves behind a ganglion (= a mass of nerves)（神经）节后的 The brain & nervous system abducens nerve abducent nerve accessory nerve alexithymia allism glossopharyngeal nerve grey matter hemispheric hemispherical hindbrain neurofibrillary neurogenic neurogenically neuroglia neuroglial reticular formation rhinencephalon rhombencephalon right brain right-brained Examples of postganglionicpostganglionic In the present study, injections of the anterior chamber were used to label the postganglionic and preganglionic afferents to the iris sphincter pupillae muscle. This extent of transsynaptic labeling was not obviously correlated with the amount of direct retrograde labeling of postganglionic neurons in the ipsilateral ciliary ganglion. These biological responses are mediated both by direct autonomic innervation of target organs by postganglionic neurons and by secretion of epinephrine and norepinephrine by the adrenal medulla. The two exceptions mentioned above are postganglionic neurons of sweat glands and chromaffin cells of the adrenal medulla.

There, they synapse with postganglionic fibers which reach the gland by hitch-hiking via the auriculotemporal nerve, a branch of the mandibular nerve.

Once inside the prevertebral ganglia, the individual neurons comprising the nerve synapse with their postganglionic neuron.

Here the fibers synapse and postganglionic fibers join the fibers of the maxillary nerve, which travels through the inferior orbital fissure.

However, the ciliary ganglion is not simply a relay station connecting "preganglionic" to "postganglionic" nerve fibers.

Sympathetic postganglionic neurons usually secrete norepinephrine and are named sympathetic adrenergic neurons.

The completion of the reflex circuit by vagus efferents leads to the stimulation of postganglionic muscarinic nerves.

By adding a large dose of nicotine, the ganglion (site of relay between pre- and postganglionic fibers) is blocked.

They play several roles, including acting as the main end-receptor stimulated by acetylcholine released from postganglionic fibers in the parasympathetic nervous system. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In response to this stimulus postganglionic neurons with two important exceptions release norepinephrine, which activates adrenergic receptors on the peripheral target tissues. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The target synapse of the postganglionic neuron is mediated by adrenergic receptors and is activated by either noradrenaline (norepinephrine) or adrenaline (epinephrine).
