Rationale for change
Rather than have it 2 sentances telling you that it is "nodes" which gives away the answer. 1 sentance is better and gets the same point across.

- In myelinated fibers, Na+/K+ channels are only found at Nodes of Ranvier.
- These channels cause the action potential to regenerate over and over along the axon, which causes the action potential to "jump" from one node to the next via saltatory conduction.
- If these nodes were not present, the action potential would propagate very slowly along the entire axon. Thus, the presence of Nodes of Ranvier allows neural transmission to occur much more quickly in myelinated axons vs. unmyelinated axons
