<P> Schwann cells ( named after physiologist Theodor Schwann ) or neurolemmocytes are the principal glia of the peripheral nervous system ( PNS ) . Glial cells function to support neurons and in the PNS , also include satellite cells , olfactory ensheathing cells , enteric glia and glia that reside at sensory nerve endings , such as the Pacinian corpuscle . The two types of Schwann cells are myelinating and nonmyelinating . Myelinating Schwann cells wrap around axons of motor and sensory neurons to form the myelin sheath . The Schwann cell promoter is present in the downstream region of the human dystrophin gene that gives shortened transcript that are again synthesized in a tissue - specific manner . </P>
