NERVE IMPULSES CONDUCTED MORE RAPIDLY IN MYELINATED NERVE FIBRES THEN THAT OF NON-MYELINATED NERVES FIBRES BECAUSE OF SALTATORY CONDUCTION.
this types of conduction occurs in myelinated nerve fibres.
this means, in effect that the action potential jumps from node to node and passes along the mylinated axon faster as compared to the series of small local circuits in a non- myelinated axon.
this type of conduction is called saltatory conduction.
leackage of ions takes place only at nodes ov Ranvier and less energy is required for saltatory conduction.
hope it will help you. ..
