The nodes of Ranvier allow for "saltatory" conduction along an axon.

Here's the step-by-step explanation:

1. The nodes of Ranvier are small gaps in the myelin sheath where the axon is exposed.

2. When an electrical signal, or action potential, is sent down the axon, it doesn't move smoothly. Instead, it jumps from one node of Ranvier to the next.

3. This type of conduction is called "saltatory" conduction, from the Latin word "saltare," which means "to leap."

4. Saltatory conduction is faster than continuous conduction because it reduces the amount of membrane that needs to be depolarized during the propagation of the action potential.

5. Therefore, the nodes of Ranvier play a crucial role in speeding up the transmission of nerve impulses.
