Saltatory conduction

📷

Summary

This animation presents the two modes of conduction of nerve messages :

  • Continuous conduction
  • Sal tatory conduction

Learning goals

  • To distinguish between continuous and saltatory conduction.
  • To understand the advantage that accrues, in terms of speed of conduction, from the presence of a myelin sheath.
  • To understand how the action potential propagates from node to node in saltatory conduction.
  • To clarify the idea of local currents and their importance in the regeneration of the action potential.

The creation  of the action potential is followed by its propagation along the length of the nerve fiber called the axon. This phenomenon is also referred to as conduction. The action potential…
