action potential

• Changement rapide et temporaire du potentiel électrique à travers la membrane cellulaire, en particulier dans les cellules nerveuses et musculaires, qui permet la transmission de signaux le long de la cellule.

A rapid, temporary change in electrical potential across a cell membrane, especially in nerve and muscle cells, that allows the transmission of signals along the cell.

   A rapid, temporary change in the electrical potential across a cell membrane, especially in nerve cells, that transmits signals.

   potentiel d'action

   • The action potential travels down the axon to the synapse.
   • Sodium ions rush into the cell during the depolarization phase of an action potential.
   • Neurons communicate by generating and propagating action potentials.
