Quizplus · Accepted Answer

The duration of a contractile response in skeletal muscle (also known as a muscle twitch) can indeed last significantly longer than the action potential that initiates it. This is because the processes of excitation-contraction coupling and cross-bridge cycling in muscle fibers take more time than the brief electrical event of the action potential.
