    Muscle Stimulation Frequency

    The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.

    At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...
