Which of the following statements concerning the properties of action potentials is TRUE?
A)The rate of propagation of an action potential down an axon is independent of stimulus strength.
B)Action potentials can undergo summation.
C)A supra-threshold stimulus can stimulate an action potential during the absolute refractory period.
D)Action potentials generally propagate from the axon terminal toward the axon hillock.
E)Increasing the size of a stimulus will increase the amplitude of an action potential.

Question

Quizplus · Accepted Answer

Action potentials have an all-or-none response, meaning their propagation rate and amplitude are not influenced by the strength of the stimulus once the threshold is reached. Summation does not apply to action potentials, they cannot be generated during the absolute refractory period, they propagate from the axon hillock towards the axon terminal, and their amplitude remains constant regardless of stimulus size.
