A common feature of action potentials is that they ________.
A) cause the membrane to hyperpolarize and then depolarize
B) can undergo temporal and spatial summation
C) are triggered by a depolarization that reaches threshold
D) move at the same speed along all axons

Question

Quizplus · Accepted Answer

Action potentials are initiated when a depolarization event (such as an influx of sodium ions) reaches a certain threshold level, prompting the rapid opening of voltage-gated ion channels and a subsequent change in membrane potential.
