Preferred Label : membrane potentials;
MeSH definition : The voltage differences across a membrane. For cellular membranes they are computed
by subtracting the voltage measured outside the membrane from the voltage measured
inside the membrane. They result from differences of inside versus outside concentration
of potassium, sodium, chloride, and other ions across cells' or ORGANELLES membranes.
For excitable cells, the resting membrane potentials range between -30 and -100 millivolts.
Physical, chemical, or electrical stimuli can make a membrane potential more negative
(hyperpolarization), or less negative (depolarization).;
MeSH synonym : transmembrane potential difference; potential difference, transmembrane; transmembrane potentials; transmembrane potential differences; potentials, membrane; potential differences, transmembrane; transmembrane potential; transmembrane electrical potential difference; potential, transmembrane; potentials, transmembrane; membrane potential; potential, membrane; difference, transmembrane potential; differences, transmembrane potential; Delta Psi;
MeSH hyponym : resting potentials; Potential, Resting; Potentials, Resting; Resting Potential; Resting Membrane Potential; Membrane Potential, Resting; Membrane Potentials, Resting; Resting Membrane Potentials;
MeSH annotation : coordinate with organ /physiol;
