Just like a neuronal action potential, a muscle action potential consists of a depolarizing phase caused by opening of voltage-gated sodium channels followed by a repolarizing phase due to opening of voltage-gated potassium channels and closing of voltage-gated sodium channels.

Question

Quizplus · Accepted Answer

The depolarizing phase caused by the opening of voltage-gated sodium channels is followed by a repolarizing phase due to the opening of voltage-gated potassium channels and closing of voltage-gated sodium channels, just like in a neuronal action potential. This same process also occurs in muscle action potentials.
