The nervous system
... Schwann cells are part of the peripheral nervous system (PNS.) They have two major functions, they produce the myelin sheath which covers the Schwann cell, which helps to repair and regenerate nerves that have been damaged. In addition, they help the nerve impulse to be passed on quicker so that the ...
