Why are nerve impulses conducted more rapidly in myelinated nerve fibre than in non-myelinated nerve fibre?

In myelinated fibres the nerve impulsejumps from one node of Ranvier to other. Thus, it is faster. However theimpulse has to travel all along the non-myelinated fibre. ... It is a process ofnerve cell body which conducts nerveimpluses away from cell body.

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. ..
