WebA series of action potentials to the muscle fibers is necessary to produce a muscle contraction that can produce work. A normal muscle contraction is more sustained, and it can be modified by input from the nervous system to produce varying amounts of force; … WebGraded potentials are fast-acting, meaning that the membrane potential typically returns to resting membrane potential quickly, within a couple msec. The opening of mechanical or ligand-gated ion channels are what induce graded potentials.
