The change in membrane potential occurring in nerve, muscle, or other excitable tissue when excitation occurs. action potential. A momentary change in electrical potential on the surface of a neuron or muscle cell. Nerve impulses are action potentials.
We will also see that in order for a neuron to generate an action potential, the membrane potential has to depolarize from the resting value of around â70 mV to the threshold value of around â50 mV. A similar situation is also at play in muscle cells (skeletal, cardiac, and smooth).
