(mī'ĕ-li-nol'i-sis),
Dissolution of the myelin sheaths of nerve fibers.
Synonym(s): myelinosis (1)
[myelin + G. lysis, dissolution]

myelinolysis

[mī′əlinol′isis]
Etymology: Gk, myelos + lysein, to loosen
a pathological process that dissolves the myelin sheaths around certain nerve fibers, such as those of the pons in alcoholic and undernourished people who are afflicted with central pontine myelinolysis.
