[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
There is an imbalance in the ions on the inside of the nerve and the outside of the nerve resulting in a negative electrical charge of approximately-70 millivolts. This is called the nerve’s:

Resting potential

BMaximum Negativity

None of the above

Explanation:
Detailed explanation-1: -The resting membrane potential of a neuron is about-70 mV (mV=millivolt)-this means that the inside of the neuron is 70 mV less than the outside. At rest, there are relatively more sodium ions outside the neuron and more potassium ions inside that neuron.
Detailed explanation-2: -Figure 4.1. For a typical neuron at rest, sodium, chloride, and calcium are concentrated outside the cell, whereas potassium and other anions are concentrated inside. This ion distribution leads to a negative resting membrane potential.
