Question

Quizplus · Accepted Answer

The threshold value for triggering a depolarization event in a nerve cell is typically around -55 mV. When the membrane potential reaches this value, voltage-gated sodium channels open, leading to rapid depolarization.

In a Nerve Cell, Crossing a Threshold Value of ___________
