WebFeb 16, 2024 · Dysfunction in forming myelin sheath in the PNS (through Schwann cells) can result in weakened reflexes, weakness, sensory loss, and sometimes paralysis. Guillain-Barre Syndrome is a peripheral demyelinating disease affecting the PNS whereby the immune system attacks healthy neurons in the PNS. WebThe PNS has two kinds of neuroglia: schwann cells and satellite cells. Schwann cells provide myelination to peripheral neurons. They also perform phagocytic functions and clear cellular debris, allowing for the regrowth of PNS neurons. Functionally, the schwann cells are similar to oligodendrocytes of the CNS.
