  1. (Anat.) One of the whitish and elastic bundles of fibers, with the accompanying tissues, which transmit nervous impulses between nerve centers and various parts of the animal body.

    Note: An ordinary nerve is made up of several bundles of nerve fibers, each bundle inclosed in a special sheath (the perineurium) and all bound together in a connective tissue sheath and framework (the epineurium) containing blood vessels and lymphatics.

  2. A sinew or a tendon.
    --Pope.

  3. Physical force or steadiness; muscular power and control; constitutional vigor.

    he led me on to mightiest deeds, Above the nerve of mortal arm.

  7. (Zo["o]l.) One of the nervures, or veins, in the wings of insects.

    Nerve cell (Anat.), a neuron, one of the nucleated cells with which nerve fibers are connected; a ganglion cell is one type of nerve cell.

    Nerve fiber (Anat.), one of the fibers of which nerves are made up. These fibers are either medullated or nonmedullated. In both kinds the essential part is the translucent threadlike axis cylinder which is continuous the whole length of the fiber.

    Nerve stretching (Med.), the operation of stretching a nerve in order to remedy diseases such as tetanus, which are supposed to be influenced by the condition of the nerve or its connections.

Wikipedia
Nerve fiber

A nerve fiber is a threadlike extension of a nerve cell and consists of an axon and (in some cases) a myelin sheath. There are nerve fibers in the central nervous system and peripheral nervous system. In the central nervous system (CNS), myelin is produced by oligodendroglia cells. Schwann cells form myelin in the peripheral nervous system (PNS). Schwann cells can also make a thin covering for an axon which does not consist of myelin (in the PNS). A peripheral nerve fiber consists of an axon, myelin sheath, Schwann cells and its endoneurium. There are no endoneurium and Schwann cells in the central nervous system.
