The theshold for firing has been reached when the electrical charge of what level of millivolts occurs within a nerve cell?
A) - 10
B) - 50
C) + 100
D) + 10

Question

Quizplus · Accepted Answer

The threshold for firing in a nerve cell is typically around -50 millivolts, so the correct answer is B. A nerve cell must reach this level of depolarization in order for an action potential, or electrical impulse, to be generated and transmitted down the axon. None of the other answer options are correct.
