NCIt definition : A supporting cell of the peripheral nervous system that aids the growth, development,
function, maintenance and repair of peripheral nerves. Myelinating Schwann cells form
the myelin sheath around large diameter axons while non-myelinating Schwann cells
bundle together portions of several unmyelinated smaller diameter axons and may also
play a role in the formation and maintenance of synaptic connections in the neuromuscular
junction.;
Alternative definition : NCI-GLOSS: A type of glial cell of the peripheral nervous system that helps separate
and insulate nerve cells.;
