which type of neuroglia surrounds axons in peripheral nerves
Schwann cells, in the peripheral nervous system, and oligodendrocytes, in the central nervous system, wrap around the axons of neurons to form myelin sheaths. Myelin sheaths are electrical insulators and prevent current from leaving axons.erve fibers are found in the peripheral nervous system and central nervous system. In the peripheral nervous system, Schwann cells form the sheath around axons, and each Schwann cell forms the sheath for just one neuron.
