Before an action potential can begin, the neuron's membrane must
A)become hyperpolarized
B)shift from a negative voltage towards a more positive voltage
C)keep the sodium ions outside the cell membrane
D)pump out the potassium ions
E)interact with glial cells

Question

Quizplus · Accepted Answer

An action potential begins when the neuron's membrane shifts from a negative voltage towards a more positive voltage. This depolarization is necessary to reach the threshold that triggers the action potential, allowing for the rapid influx of sodium ions and the subsequent electrical signal propagation.
