Examplesofpostganglionicpostganglionic In the present study, injections of the anterior chamber were used to label thepostganglionicand preganglionic afferents to the iris sphincter pupillae muscle. From theCambridge English Corpus This extent of transsynaptic labeling was not obviously correlated with the amount of direct retrograde labeling ofpostganglionicneurons in the ipsilateral ciliary ganglion. From theCambridge English Corpus These biological responses are mediated both by direct autonomic innervation of target organs bypostganglionicneurons and by secretion of epinephrine and norepinephrine by the adrenal medulla. From theCambridge English Corpus The two exceptions mentioned above arepostganglionicneurons of sweat glands and chromaffin cells of the adrenal medulla.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.The target synapse of thepostganglionicneuron is mediated by adrenergic receptors and is activated by either noradrenaline (norepinephrine) or adrenaline (epinephrine).
