Item #6 of 10

Stimulation that reverses the polarity across an axon's membrane by less than 5 millivolts _________________.

is called sub-threshold;
will not generate an action potential;
will cause slight opening of the sodium channels located in the membrane;
will allow the membrane to return quickly to its resting polarized state;
all of the alternatives provided are correct;

CORRECT - Yes, a reversal of membrane potential of less than 5 millivolts is sub-threshold. Although it will cause a slight opening of the sodium channels, it will not trigger an action potential and the membrane will quickly return to its resting state.
