neuron

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.]

neu′ro·nal (no͝or′ə-nəl, nyo͝or′-, no͝o-rōn′l, nyo͝o-), neu·ron′ic adj.
neu′ro·nal·ly adv.

neu•ron

(ˈnʊər ɒn, ˈnyʊər-)

n.
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)

Pure lower motor neuron (LMN) bulbar signs, including tongue amyotrophy or fasciculation, or neurogenic damages of EMG in tongue, sternocleidomastoid or upper trapezius muscles,[sup][12],[13] were more common in IBP compared to PBP (IBP, 42%; PBP, 20%; P = 0.
2,6,7) These criteria include evidence of lower motor neuron degeneration by clinical, electrophysiologic, or neuropathologic exam; evidence of upper motor neuron disease by clinical exam; progressive spread of symptoms or signs within a region or to other regions (by history or exam); and the absence of electrophysiologic, neuroimaging, or pathologic evidence of other disease processes that could explain the symptoms.
