The postganglionic sympathetic neurons originate in the superior cervical ganglion and travel up the wall of the internal carotid artery.
These signs indicated partial but severe right brachial plexopathy at the postganglionic level, associated with total axonotmesis of the right axillary nerve.
It contains sympathetic preganglionic fibres supplying the head and neck and sympathetic postganglionic fibres supplying the upper limb and heart (1).
The cortical cells are modified postganglionic neurones.
This discovery is first demonstration that IL-18R[alpha] exists in the peripheral nervous system, suggesting that IL-18 affects sympathetic postganglionic neurons directly, while affecting the neural-immune condition of the reproductive system in different physiological time.
* Ptosis--the position of the upper lid is determined by the relative action of the levator palpebrae superioris muscle (III cranial nerve), Muller's muscle (postganglionic sympathetic nervous system) and the orbicularis oculi muscle (VII cranial nerve).

Parasympathetic postganglionic fibers release acetylcholine and induce vasodilation and mucus production, while norepinephrine from sympathetic fibers may induce vasoconstriction by interacting with a-adrenergic receptors, which typically prevails over vasodilation induced by concomitant ligation of [beta]-receptors.
