Membrane potential (also transmembrane potential or membrane voltage) is the difference in electric potential between the interior and the exterior of a biological cell.

Nov 3, 2023 · Every cell of the body has its own membrane potential, but only excitable cells - nerves and muscles - are capable to change it and generate an action potential.

Since the membrane potential is the difference in electrical charge between the inside and outside of the cell, that difference decreases as the cell's membrane potential moves toward 0 mV.

Jul 23, 2025 · Membrane potential is the electrical potential difference across a neuron's membrane, resulting from the unequal distribution of ions such as sodium (Na+), potassium …

Any net movement of an ion across the membrane is by definition an electric current, and electric currents flowing across the membrane will alter the membrane potential.

Membrane potential is what we use to describe the difference in voltage (or electrical potential) between the inside and outside of a cell.

Membrane potential is defined as the voltage difference between the inner and outer surfaces of the cell membrane, which is critical for cell homeostasis and function in electrically excitable …

Membrane potential refers to the electrical potential difference, or voltage, that exists across a cell’s plasma membrane. This voltage arises because there is an unequal distribution of …

Membrane potential refers to the difference in charge between the inside and outside of a neuron created from unequal ion distribution on both sides of the cell membrane.

Jan 1, 2024 · Definition The electrical potential difference (voltage) across the cell membrane (plasmalemma or sarcolemma) of all living cells that is produced by an unequal net distribution …
