Gradation of muscle contraction involves varying the frequency of action potentials initiated in each muscle fibre. This is achieved by increasing or decreasing the number of action potentials that reach the muscle fibre through the motor neuron. By modulating the frequency of these action potentials, the muscle can produce varying degrees of contraction strength.
