1.Whitish bands composed of medullated nerve fibres radiating out from the optic disc are of no pathological significance and must not be confused with papilloedema.

4.This is produced throughout the body at times of inflammation and makes the body more sensitive to pain by, among other things, increasing the conductivity of nerve fibres.
