WebA motor unit is formed by a motor neuron and all of the muscle fibers that are innervated by that same motor neuron. A single contraction is called a twitch. A muscle twitch has a latent period, a contraction phase, and a relaxation phase. A graded muscle response allows variation in muscle tension. WebThe same pathway exists in cardiac muscle fibers and contributes to the increase in force and rate of relaxation produced by catecholamines via β 1 ARs. From the functional point of view, the potentiation of amplitude and/or duration of the twitch occurring in type-II muscle fibers would result in an increase in the force level developed by subtetanic contractions .
