Webbaction potential, the brief (about one-thousandth of a second) reversal of electric polarization of the membrane of a nerve cell (neuron) or muscle cell. In the neuron an action potential produces the nerve impulse, and in the muscle cell it produces the contraction required for all movement. Sometimes called a propagated potential … Webb5 mars 2024 · Additionally, simultaneous polarization and administration of HP 13 C urea and [1-13 C]pyruvate permit simultaneous interrogation of cardiac metabolism and perfusion . Because HP 13 C MRI acquisitions take only 1–2 minutes, this modality has a speed advantage over methods such as PET metabolism/perfusion mismatch studies, …

Phase 0 is depolarization of the membrane and the opening of "fast" (i.e., high-flow) sodium channels. Potassium flow also decreases. Phase 1 is partial repolarization of the membrane thanks to a rapid decrease in sodium … graphic design ability
