Question

Quizplus · Accepted Answer

The minimum stimulus required to trigger an action potential is known as the threshold. This is the point at which the depolarization of the membrane reaches a critical level that triggers the opening of voltage-gated ion channels, allowing for the rapid movement of ions and the generation of an action potential.

The Minimum Stimulus Required to Trigger an Action Potential Is
