WebThese breaks are called nodes of Ranvier. The distance between these nodes is between 0.2 and 2 mm. 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. In neuroscience and anatomy, nodes of Ranvier , also known as myelin-sheath gaps, occur along a myelinated axon where the axolemma is exposed to the extracellular space.
