Depolarization from the resting potential of -70 mV proceeds slowly until it reaches a critical level known as ____.
A)polarizing action
B)electrical action
C)depolarizing potential
D)active potential
E)threshold potential

Question

Depolarization from the resting potential of -70 mV proceeds slowly until it reaches a critical level known as ____.
A)​polarizing action
B)electrical action
C)depolarizing potential
D)active potential
E)​threshold potential

Quizplus · Accepted Answer

Depolarization from the resting potential of -70 mV proceeds slowly until it reaches the threshold potential, which is the critical level at which an action potential is fired. Therefore, the correct choice is E, threshold potential.
