What is membrane polarity?
-70 mV this potential difference in a resting neuron (Vr) is called the resting membrane potential, and the membrane is said to be polarized.
What is the inside charge of a nerve at its resting potentail?
Neurons have a resting membrane potential of approximately -70mV. Muscle cells have a resting membrane potential of approximately -90mV.
What is the approximate resting potential of a neuron?
It is -70 millivolts. The resting potential of a neuron refers to the voltage difference across the plasma membrane of the cell, and is expressed as the voltage inside the membrane relative to the voltage outside the membrane. The typical resting potential voltage for a neuron is -70mV Resting potentials occur because of the difference in concentration of ions inside and outside of the cell, largely by K+ (Potassium ions) but some contribution is made by Na+(Sodium ions)
What is the magnitude amplitude of an action potential?
The amplitude is about +35 to +40 Millivolts I believe this is incorrect, as this would only raise the resting membrane potential from -70mV to -35 or -40. An action potential needs to raise the membrane potential from -70 mV to +30 mV, so the amplitude needs to be 100 mV.
What is the value for the resting membrane potential for most neurons?
-200 to -18omV, if i am wrong, kindly post the corrected one

When at rest the axon membrane has an electrical charge of?
When at rest, the axon membrane has a negative electrical charge inside compared to outside. This is known as the resting membrane potential and is typically around -70 millivolts.
What is resting potential?
A rest potential is the potential difference between two sides of the membrane of nerve cells when the cell is not conducting an impulse. =)

Is the resting potential of a neuron approximately -70 microvolts?
Yes, the resting potential of a neuron is typically around -70 millivolts (mV), not microvolts. The resting potential is the membrane potential of a neuron when it is not being stimulated to send a signal.

The resting potential of a neuron is approximately?
The resting potential of a neuron is approximately -70 millivolts. This is due to the difference in charge across the neuron's membrane, with the inside being more negatively charged compared to the outside.
What characterize repolarization the second phase of the action potential?
Once the membrane depolarizes to a peak value of +30 mV, it repolarizes to its negative resting value of -70 mV.
