repolarization
repolarization [re″po-lah-rĭza´shun] 1. the reestablishment of polarity, especially the return of a cell's potential" >membrane potential to potential" >resting potential after depolarization.2. in cardiac physiology, the restoration of the cell to its maximal potential" >diastolic potential, represented by phase 0 to phase 3 of the action potential.re·po·lar·i·za·tion (rē'pō-lăr-i-zā'shŭn), The process whereby the membrane, cell, or fiber, after depolarization, is polarized again, with positive charges on the outer and negative charges on the inner surface.repolarization (rē-pō′lər-ĭ-zā′shən)n. The restoration of a polarized state across a membrane, as in a muscle fiber following contraction.re·po·lar·i·za·tion (rē-pō'lăr-ī-zā'shŭn) The process whereby the membrane, cell, or fiber, after depolarization, is polarized again, with positive charges on the outer and negative charges on the inner surface. repolarization Restoration of the resting polarized state in a muscle or nerve fibre. Polarization implies a balanced electrical charge on either side of the fibre membrane, being, in the resting state, negative on the inside and positive on the outside. In depolarization the charges are locally reversed. |
