The resting potential is:
A)the length of time that a neuron is incapable of activating after an action potential.
B)the term used to describe how the sympathetic nervous system reduces arousal and conserves energy.
C)a state in which a neuron has a negative electrical charge of about -70 millivolts.
D)a state in which a neuron has a positive electrical charge of +70 millivolts.

Question

Quizplus · Accepted Answer

The resting potential is the state in which a neuron has a negative electrical charge of about -70 millivolts. This is the baseline state of a neuron when it is not actively transmitting signals. Option A is incorrect as it describes "refractory period" which is the time period after an action potential during which the neuron cannot be stimulated. Option B is incorrect as it describes the parasympathetic nervous system's response and not the resting potential. Option D is incorrect as a neuron never has a positive electrical charge of +70 millivolts, so it does not make sense.
