membrane potential meaning
[Medicine]
Ratio of inside versus outside concentration of potassium,sodium,chloride and other ions in diffusible tissues or cells. Also called transmembrane and resting potentials,they are measured by recording electrophysiologic responses in voltage-dependent ionic channels of (e.g.) nerve,muscle and blood cells as well as artificial membranes.n : the difference in electrical potential between the interior of a cell and the interstitial fluid beyond the membrane

Examples
More: Next- a change in membrane potential affects the orientation of charged molecules.
- during the course of the upstroke, the membrane potential attains zero, and an electrical gradient no longer exists.
- the membrane potential across charged membranes
- bkca channels were activated firstly at 0 . 05 u mol / l [ ca2 + ] i with membrane potential of + 20mv
- berberine-induced changes of mitochondria membrane potential and free intracellular calcium of hacat cells
