action potential

• Mudança rápida e transitória do potencial elétrico através da membrana de uma célula, especialmente neurônios e células musculares, que permite a condução de sinais ao longo da célula.

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.

1. Neural signalC1formal

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

   Potencial de ação

   • 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.
