The peripheral nervous system has the ability to regrow cut nerves. Motor axons preferentially reinnervate motor pathways. The tendency of motor axons to reinnervate motor pathways instead of cutaneous pathways is influenced by a number of factors in the PNS system. Some factors include Schwann cell characteristics, neurotrophic factors, and nerve branch size. These factors influence the pathway preference of the motor neuron.
