Definition
English
:
The lipid-rich sheath surrounding
AXONS
in both the central and peripheral nervous systems. The
myelin sheath
is an electrical insulator and allows faster and more energetically efficient
conduction
of impulses. The sheath is formed by the cell
membranes
of glial
cells
(SCHWANN
CELLS
in the peripheral and
OLIGODENDROGLIA
in the central nervous system). Deterioration of the sheath in
DEMYELINATING DISEASES
is a serious clinical problem.
