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.

Furthermore, several studies have shown that the arbours of small-diameter primary C-fibre afferents can enlarge greatly in rats and mice after SCI potentially leading to increased reflex excitation of preganglionic neurons, via interneuronal pathways.
Electromyography disclosed involvement of the left S1 root (gastrocnemius muscle had 2+ waves with mild decreased motor unit numbers) and corresponding paraspinal muscles suggestive of preganglionic damage; sensory and motor conduction was normal.
In 1971, hydroxyamphetamine (Paredrine) was readily available and widely used and therefore chosen as the drug of choice to distinguish between postganglionic and preganglionic or central causes of oculosympathetic palsy (OSP).
Orexins/hypocretins excite rat sympathetic preganglionic neurons in vivo and in vitro.
The preganglionic parasympathetic fibers of the 3rd nerve which are transported by the nerve to the inferior oblique muscle arrive to the ciliary ganglion and from here the post-ganglionic parasympathetic fibers emerge.

The first related to the anatomical pathways: sympathetic impulses are carried from the sympathetic spinal centres to the sympathetic ganglia by preganglionic B- fibres, which are partially myelinated and thus the greater lipid solubility of ropivacaine may account for the shorter duration of action of the former.
