    Glial Cells of the PNS

    The Schwann Cell

    The Schwann cell is the myelinating cell of the PNS. In contrast to the oligodendrocyte of the CNS, which uses multiple processes to myelinate multiple segments of axons, a Schwann cell provides myelin for a single segment of an axon. Still, the appearance and function of myelin in the PNS is exactly the same as the CNS.

    The Satellite Cell

    Satellite glial cells help regulate the external chemical environment around neurons of the PNS. In this way, they are very similar to the astrocyte of the CNS but, in addition, are highly sensitive to injury and inflammation.
