Schwann cells are glia that myelinate the neurons of the Peripheral Nervous System
The Remaining Schwann Cells schwann cells, after injury and disruption to target, the remaining schwann cells undergo a rapid mitotic division until the target tissue is reached and the successful pathway is regenerated under the structural guidance of the schwann cells,
