The movement of an impulse from one node of Ranvier to the next is termed saltatory conduction.

Here's why:

* Nodes of Ranvier: These are gaps in the myelin sheath that insulates axons.

* Saltatory Conduction: The impulse "jumps" from one node to the next, skipping over the myelinated segments. This is a much faster way for the signal to travel compared to continuous conduction along unmyelinated axons.

Let me know if you'd like more details about how saltatory conduction works!
