AP PSYCHOLOGY

Detailed explanation-1: -A neuron at rest is negatively charged: the inside of a cell is approximately 70 millivolts more negative than the outside (−70 mV, note that this number varies by neuron type and by species).

Detailed explanation-2: -Neurons actually have a pretty strong negative charge inside them, in contrast to a positive charge outside. This is due to other molecules called anions. They are negatively charged, but are way too big to leave through any channel. They stay put and give the cell a negative charge inside.

Detailed explanation-3: -At rest, a typical neuron has a resting potential (potential across the membrane) of −60 to −70 millivolts. This means that the interior of the cell is negatively charged relative to the outside.

Detailed explanation-4: -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.

Detailed explanation-5: -What is the resting potential of neuron? The resting potential of a neuron is the electrical potential difference between the inside and outside of a neuron. The inside is more negative and the outside is more positive, creating a resting potential of approximately-70 mV.
