 Context examples 

Hydroxyamphetamine, when applied topically to the eye, stimulates the release of norepinephrine from postganglionic adrenergic nerves resulting in the stimulation of both alpha and beta adrenergic receptors.

(Hydroxyamphetamine, NCI Thesaurus)

Catecholamines are hormones and neuromodulators synthesized in the chromaffin cells of the adrenal glands and the postganglionic fibers of the sympathetic nervous system in response to stress.

(Catecholamine, NCI Thesaurus)

Ipratropium antagonizes the actions of acetylcholine at parasympathetic postganglionic effector cell junctions.

(Ipratropium, NCI Thesaurus)

Ipratropium antagonizes the actions of acetylcholine at parasympathetic, postganglionic, effector-cell junctions.

(Ipratropium Bromide, NCI Thesaurus)

The abnormally dilated pupil is caused by damage to postganglionic parasympathetic fibers innervating the eye.

(Holmes-Adie Syndrome, NCI Thesaurus)

Pathologic features include degeneration of the ciliary ganglion and postganglionic parasympathetic fibers that innervate the pupillary constrictor muscle.

(Holmes-Adie Syndrome, NLM, Medical Subject Headings)

Upon oral administration, hyoscine butylbromide binds to and blocks muscarinic receptors located on postganglionic parasympathetic nerve endings and on smooth muscle cells.

(Butylscopolamine Bromide, NCI Thesaurus)

In the autonomic ganglia, the preganglionic fibers from the central nervous system synapse onto the neurons whose axons are the postganglionic fibers innervating target organs.

(Autonomic Ganglion, NLM, Medical Subject Headings)

Expressed in effector tissues innervated by postganglionic sympathetic adrenergic fibers, Alpha Adrenergic Receptor Genes encode Alpha Adrenergic Receptors, one of two major classes of adrenergic receptors (alpha and beta) based on their reactions to norepinephrine and epinephrine, on cellular effects of receptor activation, and on relative affinities and reactions to synthetic blocking or stimulating agents.

(Alpha Adrenergic Receptor Gene, NCI Thesaurus)

Expressed by Beta Adrenergic Receptor Genes in effector tissues innervated by postganglionic sympathetic adrenergic fibers, Beta Adrenergic Receptors are one of two major classes of adrenergic receptors (alpha and beta) based on their reactions to norepinephrine and epinephrine, on cellular effects of receptor activation, and on relative affinities and reactions to synthetic blocking or stimulating agents.

(Beta Adrenergic Receptor, NCI Thesaurus)
