    Dear Teachers,

    I read this from 29 Gifts by Cami Walker:

    "In the case of Multiple sclerosis, the immune system attacks the myelin, a protective fatty layer surrounding the nerves. Think of it as insulation that keeps the nerves firing smoothly. ... I imagine little holes being eaten in my nerve linings that leave areas of raw, exposed nerve prone to misfiring."

    What do "fire" and "misfre" mean in this context?

    27. to discharge (a gun).
    to project (a bullet or the like) by or as if by discharging from a gun.

    Discharge is probably a more appropriate word, but 'fire' is the word used to describe the stimulation of a nerve in the body to send it's action potential (electrical signal). Misfire is the opposite, i.e. a nerve which doesn't release it's action potential (or in the case of Multiple Sclerosis, releases the signal, but it fails to reach the nerve ending.)
