What happens if the PNS is damaged?

Symptoms of PNS damage include problems with sexual function, bladder control, blood pressure regulation, digestion and loss of sensation in the hands and feet. Schwann cells provide the myelin sheath (insulation) for the nerve cells that carry electrical signals to and form the spinal cord.
