Question

Quizplus · Accepted Answer

Repolarization occurs once the peak of the action potential is reached and the membrane potential begins to move back toward the resting potential.

Answer: F
 Absolute refractory period occurs during the time when the membrane potential is moving from depolarization to repolarization, and the membrane cannot respond to a stimulus no matter its strength.

Answer: C
 Rapid depolarization occurs when the membrane potential reaches threshold and sodium ions rapidly enter the cell, leading to a sharp increase in the membrane potential.

Answer: E
 Relative refractory period occurs once the membrane potential is returning toward the resting potential, but the threshold for the action potential is much higher than under normal conditions.

Answer: A
 Polarization occurs when the membrane potential is at rest and is maintained by the sodium-potassium pump.
