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·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)

Known as "central drive," (7) these impulses arise from supraspinal motor areas (the motor cortex and subcortex) and descend through the spinal cord to the peripheral motor neuron pool governing the muscles involved in the activity.
