depolarization

• Processus impliquant la perte ou la diminution de la polarité ou de la polarisation, souvent lié à un changement de charge électrique à travers une membrane cellulaire.

A process involving the loss or reduction of polarity or polarization, often referring to a change in electrical charge across a cell membrane.

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.

   Dépolarisation membranaire

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