Question

Quizplus · Accepted Answer

The jumping of an action potential from one node of Ranvier to the next is called saltatory conduction. This is because the action potential appears to "jump" from node to node, rather than traveling continuously along the entire axon. This process is faster and more efficient than continuous conduction (also known as point to point conduction), which occurs in unmyelinated axons. Refractory conduction and summary conduction are not accurate terms used to describe this phenomenon.
