====== Nerve ======
A nerve is an enclosed, cable-like bundle of [[axon]]s in the [[peripheral nervous system]]. 

A [[nerve root]] (latin: radix nervi) is the initial segment of a [[nerve]] leaving the [[central nervous system]].

====Function====
A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the [[axon]]s to peripheral organs.

In the [[central nervous system]], the analogous structures are known as [[tract]]s.

Neurons are sometimes called nerve cells, though this term is potentially misleading since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.

Each nerve is a cordlike structure that contains many axons, also called nerve fibres. Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium. The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium. Finally, the entire nerve is wrapped in a layer of connective tissue called the epineurium.
