Which of the following is TRUE regarding action potentials?
A)Partial action potentials result in fewer neurotransmitter molecules being released than whole action potentials.
B)Action potentials operate under the "all-or-none law," which means that action potentials either move all sodium ions across the membrane or none of the sodium ions across the membrane.
C)Once an action potential is started, it is self-sustaining and continues to the end of the axon.
D)Action potentials regenerate themselves during their refractory periods when the axon membrane is depolarized.

Question

Quizplus · Accepted Answer

Action potentials are self-sustaining once initiated, propagating along the axon to its end. This is due to the sequential opening of voltage-gated ion channels along the axon's length.
