WebFeb 24, 2024 · Normal muscle contraction is more sustained, and it can be modified by input from the nervous system to produce varying amounts of force; this is called a graded muscle response. The frequency of action potentials (nerve impulses) from a motor neuron and the number of motor neurons transmitting action potentials both affect the tension … 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. greatpeoplesearch reverse phone
