MUSCLE PHYSIOLOGY

Detailed explanation-1: -Fused tetanus is when there is no relaxation of the muscle fibers between stimuli and it occurs during a high rate of stimulation. A fused tetanic contraction is the strongest single-unit twitch in contraction. When tetanized, the contracting tension in the muscle remains constant in a steady state.

Detailed explanation-2: -Tetanus causes painful muscle contractions. Complete tetanus is also called fused tetanus. During complete tetanus, there’s no relaxation period between muscle contractions. Your muscle contractions completely fuse to create one continuous muscle contraction.

Detailed explanation-3: -Complete 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.

Detailed explanation-4: -During incomplete tetanus, the muscle goes through quick cycles of contraction with a short relaxation phase for each. If the stimulus frequency is so high that the relaxation phase disappears completely, contractions become continuous in a process called complete tetanus ([link]b).
