axon

[C] 可算名詞

複数形: axons

This term carries a clinical and precise connotation, used almost exclusively in biological, medical, or neurological contexts. It evokes the image of a biological cable or a transmission line, emphasizing the unidirectional flow of information within the nervous system. While dendrites receive signals, the axon is the active transmitter. The terminology suggests a structural rigidity and a specific purpose of distance, distinguishing the long-range transport of the axon from the local processing occurring in the cell body.

Countable when referring to the individual projections of specific neurons in a histological sample.
