PATHOLOGY

Detailed explanation-1: -Action potentials traveling down the axon “jump” from node to node. This is called saltatory conduction which means “to leap.” Saltatory conduction is a faster way to travel down an axon than traveling in an axon without myelin.

Detailed explanation-2: -In white fibres that are myelinated axons, impulse jumps from Node of Ranvier to another, it is called saltatory conduction.

Detailed explanation-3: -The propagation of electrical impulses along axons is highly accelerated by the myelin sheath and produces saltating or “jumping” action potentials across internodes, from one node of Ranvier to the next.
