When the axon is at rest, the inside of the neuron has a charge that is 70 millivolts more negative than the outside. This difference will continue as long as
A) the neuron's receptor continues to be stimulated.
B) the impulse is past the recording electrode.
C) signals remain in the neuron.
D) the neuron is at rest.

Question

Quizplus · Accepted Answer

The resting potential, or the difference in charge between the inside and outside of the neuron, is maintained as long as the neuron is at rest. When the neuron receives a signal, the resting potential may temporarily change, but it will return to its resting state once the signal has passed. Choice A, B, and C are incorrect because they do not fully explain the maintenance of the resting potential.
