neu·ron

 (no͝or′ŏn′, nyo͝or′-)
n.
1. Any of the impulse-conducting cells that constitute the brain, spinal column, and nerves in vertebrates, consisting of a nucleated cell body with one or more dendrites and a single axon.
2. A similar impulse-conducting cell in invertebrates. In both senses also called nerve cell.

[Greek, sinew, string, nerve; see (s)neəu- in Indo-European roots.]

a specialized, impulse-conducting cell that is the functional unit of the nervous system, consisting of the cell body and its processes, the axon and dendrites.
Also called nerve cell. Also, esp. Brit.,neu•rone (-oʊn)

Should a lesion that causes OSP affect the preganglionic neuron, MAO in the postganglionic neuron will still inactivate any adrenaline or NA present and, despite denervation hypersensitivity, neither pupil will dilate after the instillation of adrenaline 1:1 000.
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.
Orexins/hypocretins excite rat sympathetic preganglionic neurons in vivo and in vitro.
