The nerve fiber is insulated by a spiral layer called myelin, which is produced in both CNS and PNS. The myelinated cells conduct signals in a distinct manner known as saltatory conduction, saltatory means “jumping” or “leaping”. These myelinated fibers are unable to conduct the signal continuously. The major part of the axon is covered by myelin; conduction happens in the fast internodal process. This is the reason why myelinated fibers conduct signal much faster than the unmyelinated fibers.
