The “jumping” of an impulse between the “Nodes of Ranvier” thus dramatically increasing it’s speed.
Only occurs in axons having Myelin.
2m/s 120 m/s
If an axon is stimulated above its threshold it will trigger an impulse down its length.
The strength of the response is not dependent upon the stimulus.
An axon cannot send a mild or strong response. It either responds or does not!!!
