Electrical signals travel faster in axons that are insulated with myelin. ... 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.

Why is saltatory conduction more efficient?

Saltatory conduction occurs in myelinated axons from one node of Ranvier to the next node. Therefore, the action potential is only generated at the neurofibrils in myelinated axons. Hence, it is faster than continuous conduction.

What is true about saltatory conduction?

Saltatory conduction is slower than continuous propagation. ... Saltatory conduction involves the generation of action potentials at each node of Ranvier.
