<prompt> Non-myelinated axons differs from myelinated in that they:Are more excitableLack node of RanvierAre capable of regenerationAre not associated with Schwann cells  <response>: Remember, two types of Schwann cell: Myelinating and nonmyelinating types.In the PNS, unmyelinated axons are surrounded by Schwann cells nonmyelinating, whereas myelinated axons are ensheathed by multiple wrapped membranes of Schwann cells, much as the oligodendroglia, that ensheath central axons.
