Once an action potential is generated, it propagates down the length of the axon whether or not the stimulus continues. True False
Adi S.
Which of the following is true with regard to the action potential? (A) All hyperpolarized stimuli will be carried to the axon terminal without a decrease in size. (B} The size of the action potential is proportional to the size of the stimulus that produced it. (C) Increasing the intensity of the depolarization increases the size of the impulse. (D) Once an action potential is triggered, an impulse of a given magnitude and speed is produced.
