action potential

• Kurzzeitige Änderung des elektrischen Membranpotentials erregbarer Zellen wie Nerven- oder Muskelzellen, die der Weiterleitung von Signalen dient.

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.

   Nervensignal

   • 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.
