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

• Continuous conduction
• Sal tatory conduction

• 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.
