Detailed explanation-1: -Saltatory conduction describes the way an electrical impulse skips from node to node down the full length of an axon, speeding the arrival of the impulse at the nerve terminal in comparison with the slower continuous progression of depolarization spreading down an unmyelinated axon.

Detailed explanation-2: -Simply put the impulse jumps from one node to the other node, hence called Saltatory Conduction. Even though strictly speaking, the signal doesn’t jump from one node to another, there is some moderately complex stuff going on in the background, during this type of conduction.

Detailed explanation-3: -It is also known as node-to-node conduction since myelin sheath is absent in this region(nodes are the gaps along the axonal sheath). It is the neural conduction from node to node.

Detailed explanation-4: -This rapid conduction of electrical signal reaches the next node and creates another action potential, thus refreshing the signal. In this manner, saltatory conduction allows electrical nerve signals to be propagated long distances at high rates without any degradation of the signal.
