Neurons have a resting membrane potential of approximately -70mV.
Muscle cells have a resting membrane potential of approximately -90mV.
-70 millivolts.
Inside a resting neuron, there is a higher concentration of potassium ions compared to sodium ions. This creates a negative resting membrane potential that is essential for conducting nerve impulses. Additionally, there are large concentrations of negatively charged proteins within the neuron that contribute to the overall negative charge inside the cell.
When an axon is not conducting a nerve impulse and there is a higher concentration of sodium ions outside the axon and a higher concentration of potassium ions inside, it is referred to as the resting potential. During this state, the axon's membrane is polarized, with a negative charge inside relative to the outside. This resting potential is crucial for the generation of action potentials when the neuron becomes activated.
The restoration of the original charge to a nerve cell is called repolarization. This process involves the movement of ions across the cell membrane to reset the cell's resting membrane potential.
The major intracellular ion involved in polarization is potassium (K+). During the resting state of a cell, potassium ions are more concentrated inside the cell compared to the outside, contributing to the negative charge inside the cell relative to the outside. This difference in ion concentration is crucial for maintaining the resting membrane potential and is essential for the proper functioning of nerve and muscle cells during action potentials.
-70 millivolts.
A resting nerve fiber is polarized because the concentration ofNa+ is higher on the outside and K+ is higher on the inside.
Inside a resting neuron, there is a higher concentration of potassium ions compared to sodium ions. This creates a negative resting membrane potential that is essential for conducting nerve impulses. Additionally, there are large concentrations of negatively charged proteins within the neuron that contribute to the overall negative charge inside the cell.
There is a slight difference in electrical charge between the inside and outside of a nerve cell membrane, known as the resting membrane potential. This potential is typically around -70 millivolts, with the inside of the cell more negative compared to the outside. This difference in charge is essential for the nerve cell to transmit electrical signals.

At rest, the nerve membrane is referred to as polarized, meaning there is a difference in electrical charge between the inside and outside of the cell. This difference is maintained by the sodium-potassium pump, which actively transports ions across the cell membrane.
When an axon is not conducting a nerve impulse and there is a higher concentration of sodium ions outside the axon and a higher concentration of potassium ions inside, it is referred to as the resting potential. During this state, the axon's membrane is polarized, with a negative charge inside relative to the outside. This resting potential is crucial for the generation of action potentials when the neuron becomes activated.
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.

The resting nerve cell is not being stimulated to send a nerve impulse
Maintenance of a polarized state of a resting nerve is achieved through continuous expenditure of energy.
The major intracellular ion involved in polarization is potassium (K+). During the resting state of a cell, potassium ions are more concentrated inside the cell compared to the outside, contributing to the negative charge inside the cell relative to the outside.
