Web7 Jul 2024 · A tetanic contraction (also called tetanized state, tetanus, or physiologic tetanus, the latter to differentiate from the disease called tetanus) is a sustained muscle … WebComplete tetanus, also called fused tetanus, occurs when the frequency of stimuli increases still further (refer to Figure 1d). In this case, individual muscle contractions completely fuse to produce one large muscle contraction. Strength of stimulus. Muscle contractions intensify when more motor neurons stimulate more muscle fibers.
