Abstract:
Peripheral nerve injury has many causes ranging from traumatic damage to metabolic
disturbances (e.g.in diabetes mellitus). The primary pathology can affect axons (nerve
transection) or Schwann cells, and their interdependence means that injury to one will ultimately
affect the other. Fortunately, the PNS has a significant capacity for repair, and axons are able to
regenerate over long distances and are also capable of remyelination.
