A handheld remote controller placed against the cheek activates the device and controls the intensity of stimulation, which is thought to work by blocking signals to the postganglionic
After separation from the superior cervical ganglion, postganglionic
and sympathetic fibers are separated into two groups together with carotis communis bifurcation.
Reserpine mediates the depletion of neurotransmitters from postganglionic
nerve endings, which consequently lower arterial pressure and total peripheral resistance ultimately leading to decreased heart rates and cardiac output.
The extensive nerve network in the submucosa contains visceral sensory fibers mainly of sympathetic origin, parasympathetic (terminal) ganglia, and preganglionic and postganglionic
parasympathetic nerve fibers.
Nerve fibers consistent with postganglionic
sympathetic fibers were also found close to blood vessels, which again suggests a vascular component leading to ischemic pain.
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).
In such cases, irritation of cranial nerves V and VII and the sympathetic postganglionic
fibers of the superior cervical ganglion might have caused the symptoms associated with cluster headache.
Adenosine triphosphate (ATP) is released from parasympathetic postganglionic
fibres, as well as ACh.
Facial sweating was preserved and ocular movements were intact with no diplopia or other cranial nerve or long tract deficit, in keeping with a left postganglionic
Neuroblastoma is a tumour of the postganglionic
sympathetic neurons and is the most common extracranial solid tumour of childhood with a prevalence of about 1 case per 7000 births.
Hemodynamic and neurohormonal effects of clonidine in patients with preganglionic and postganglionic
Acetylcholine is released in all preganglionic autonomic nerves, all postganglionic
parasympathetic and some sympathetic nerves, nerves to the adrenal medulla, somatic motor nerves to skeletal muscles and some neurones in the central nervous system.
