Question

Complete tetanus occurs when the rate of stimulation is so high that the muscle is unable to relax at all, resulting in a sustained contraction. This is different from incomplete tetanus, where the muscle does experience some periods of relaxation between contractions. Wave summation refers to the increase in tension produced by a muscle fiber when a second stimulus is applied shortly after the first, before the muscle has fully relaxed. Therefore, the best choice is A, complete tetanus.
