In neurоmusculаr physiоlоgy, the strength of а muscle contrаction is determined by the number of motor units activated in response to a stimulus. As stimulus intensity increases, additional motor units are recruited to generate stronger contractions. A maximal stimulus is the lowest stimulus intensity that recruits all available motor units within a muscle, producing the greatest force of contraction. Any stimulus intensity beyond this point, termed supramaximal, does not result in increased muscle force because no additional motor units remain to be activated. Question Which of the following best defines a maximal stimulus?
