015 Saltatory Conduction

Leslie Samuel explains saltatory conduction, a process that speeds up the action potential along the axon. He describes how voltage gated sodium channels open to allow sodium ions in, which then move quickly along the axon. Using an analogy of taking steps, he illustrates how the action potential jumps between nodes of Ranvier, bypassing the slower process of channel opening. This jumping mechanism, facilitated by myelin sheaths, allows for rapid signal transmission. The video concludes with an invitation for questions and comments.
