Nerve

A nerve is an enclosed, cable-like bundle of peripheral axons (the long, slender projections of neurons).

In the central nervous system, the analogous structures are known as tracts. Neurons are sometimes called nerve cells, though this term is technically inaccurate since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.
