Continuous conduction of action potentials means that
A) once an action potential is created, it moves in both directions along the axon.
B) the whole axon depolarizes at the same time.
C) an action potential in one site generates local currents causing depolarization to threshold at the adjacent site.
D) an action potential is conducted from one node of Ranvier to the next node.

Question

Quizplus · Accepted Answer

Continuous conduction of action potentials involves the generation of an action potential at one site on a neuron's membrane, which then causes local currents that depolarize the adjacent area of the membrane to threshold, thereby generating a new action potential in that area. This process repeats along the length of the axon, allowing the action potential to propagate continuously along the axon.
