Definition
English
:
The lipid-rich sheath surrounding AXONS in both the CENTRAL NERVOUS SYSTEMS and
PERIPHERAL NERVOUS SYSTEM
. 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.
