Why is action potential important for muscle contraction?

Posted October 16, 2023


Action potential is a special type of electrical signal that travels along a muscle cell membrane as a wave and causes a fast, fleeting reversal of electric polarization of the muscle cell membrane. Muscle contraction would not be possible in the absence of action potential.
