Myelin deposition in the PNS may result in a single axon having up to 100 myelinlayers; therefore, it is improbable that myelin is laid down by a simple rotation of the Schwann cell nucleus around the axon. In the CNS, such a postulate is precluded by the fact that one glial cell can myelinate several axons.

Dear student 
 CNS and PNS have both types of neurons, myelinated and non myelinated.
But in PNS majority are non myelinated and in CNS myelinated.
