Since the axon is exposed, the signal gets lost and does not make it to the muscle end plates. Astrocytes repair nervous system after incident, maintain. The word myelin is the describing word for the sheath. Myelin sheath are made up of schwann cells. Clean up any kind of debris, anything that shouldn"t be there, like disease and waste from other types of cells. Active immune defense and protect in bbb functions.
