1. Loss of polarityC1formalscientific

   The process by which the electrical charge across a cell membrane becomes less negative, reducing the difference in charge between the inside and outside of the cell.

   Despolarización (pérdida de polaridad)

   • Depolarization of the neuron triggers an action potential.
   • The influx of sodium ions causes membrane depolarization.
   • Cardiac muscle depolarization is essential for a heartbeat.
