fibers join branches of the mandibular nerve (primarily the auriculotemporal and buccal nerves) to supply the parotid gland and nearby mucous glands with secretomotor fibers and also supply the vasculature with vasodilator fibers.
In our case, in which anesthesia was managed only with propofol, the levels of catecholamine and cortisol were also not elevated by pain stimuli (Table 1); however, it has been pointed out that catecholamine levels might not be elevated by stress induction because of the loss of postganglionic
sympathetic fibers in patients with CIPA .

failure with mild sudomotor and severe cardiovagal and adrenergic impairment probable distal on this study.

In these studies, the stimuli were applied to the postganglionic
Preganglionic neurons release the neurotransmitter acetylcholine, which stimulates postganglionic
neurons to release noradrenaline directly into the blood ensuring that all cells in the body's nervous and endocrine systems have been activated.
Caption: The implantable sphenopalatine ganglion stimulator is thought to work by blocking signals to the postganglionic
parasympatheic fibers, which innervate facial structures.
Study done by PK Devarbhavi et al has shown that hypertension is one of the commonest cardiovascular manifestations of scorpion sting envenomation; this is due to massive outpouring of catecholamines from adrenal medulla and also from postganglionic
The goal of imaging the BP is to visualize the entire course of the neural network from its preganglionic segments (eg, nerve rootlets and intraforaminal nerve segments) and the postganglionic
segments from the dorsal root ganglion (DRG) to the terminal branches.
showed the daily variation of melatonin pineal gland content and proposed that the neural pathway that links the retina to the pineal gland involves sympathetic postganglionic
fibres originated in the superior cervical ganglia .
