Question

Quizplus · Accepted Answer

70 millivolts is the typical resting potential of a neuron, while 55 millivolts is the threshold of excitation - the point at which a neuron becomes sufficiently depolarized to generate an action potential. Therefore, choice A is the correct answer. Choices C and D are not related to neurophysiology and choice B is incorrect as it has the order reversed.
