Myelinated nerve fibres are covered by myelin sheath . And myelin sheath is current resistant layer. That is only possible way of transfer of current is through nodes of Ranvier. That is impulse can jump faster only through these nodes.
While non myelinated has no myelin sheath so current has to be conducted through each region and current cannot jump and that's the answer

Your answer is way too good.
thanks.
Bye,take care.
there is scientific term to it i forgot.
No worries frnd, its ok.
i got the term saltatory conduction
Thank u so much frnd
U are such a helpful person
wlcm
Thank u for lendin gyour pescious time to me.

Voltage gated sodium ion channels are confined to the nodes. The influx of sodium ions at one node creates enough depolarization to reach the threshold of the next. This means that the action potential 'jumps' from one node to the next. The process is known as saltatory conduction and results in much faster propagation of the nerve impulse compared to non-myelinated neurons where action potentials travel as one slow wave.
