-
Term used to designate the secondary degeneration in nerve fibers which ensues when these fibers are cut off from their cells; so-called from the English neurologist, Waller, who first described the process satisfactorily. During the degeneration the axis cylinder and myeline sheath disappear completely and nerve fibers are formed subsequently by the growth of the neurilemmal nuclei and the down growth of the axis cylinder from the intact central stump of the nerve.
