postganglionic

Pertaining to the nerve fibres whose cell bodies are in the ganglia of the AUTONOMIC NERVOUS SYSTEM, and to any synaptic connection with these fibres. The ganglia are collections of the bodies of neurons whose axons conduct impulses peripherally. Compare PREGANGLIONIC.

postganglionic

123]I-MIBG is used in the United States as a radiotracer in cardiac scintigraphy to diagnose the presence of a pheochromocytoma (an adrenal gland tumor), as it allows the detection and functional assessment of postganglionic noradrenergic neurons (Joyce, Rizzi, Calo, Rowbotham, & Lambert, 2002; King, Mintz, & Royall, 2011; Maxwell, 1982).
The medulla is well defined, in the centre of the gland, intimately connected with the adrenal cortex, with groups of large chromaffine cells disposed in short, irregular cords, together with isolated scattered postganglionic parasympatethic neurons.
Cholinergic neurons in the PNS comprise motor neurons, postganglionic parasympathetic neurons, and preganglionic sympathetic and parasympathetic neurons.
Postganglionic neurons release noradrenaline, which binds to beta-adrenoreceptors in the detrusor, leading to detrusor relaxation (Andersson, 2007).
