摘要
Schwann cells are glial cells in the peripheral nervous system that provide trophic support for the growth and maintenance of sensory,motor,and autonomic neurons and ensheath their axons in either a myelinating or an unmyelinating form.Myelinating Schwann cells wrap around largedia meter axons to form m ultilayered myelin structures essential for the rapid action potential propagation from one node of Ranvier to the next node(saltatory conduction).
