 (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.]
