Which of the following situations correctly illustrates the all-or-none principle? Select one: a. A smaller voltage change will result in a smaller nerve impulse. b. A stronger impulse can be generated by increasing the number of open voltage-gated sodium channels during depolarization. c. A greater voltage change and a smaller voltage change will result in the same action potential as long as the threshold potential has been reached. d. A faster impulse can be generated with a voltage change that is greater than the threshold potential.
