relaxation phase
Tetanus, also known as fused or complete tetanus, occurs when stimuli arrive so rapidly that twitches merge into a sustained contraction. This leads to continuous muscle tension and the inability for the muscle to relax. It is different from the normal twitch response to individual stimuli.
The total force that a muscle generates during a stimulated twitch depends on the frequency and intensity of the stimulation. In general, as the stimulation frequency increases, the force generated by the muscle also increases up to a point, where it reaches a plateau known as tetanus. After this point, increasing the stimulation frequency further does not significantly increase the force output.
A muscle twitch is an involuntary contraction of a muscle group without conscious effort.
If you exercise that particular muscle, the twitch should go away.
in wave summation muscular fibers recieve second stimulus after a refractory period and before fiber relaxes while in tetanus the fiber receives 20-30 stimuli per second and it relax partialy.
cutaneous muscle
The three type of muscle fibers are fast-twitch, slow-twitch, and hybrid.
slow twitch and fast twitch
Slow twitch and fast twitch A muscle fibers.
Slow twitch muscle fibers have more mitochondria compared to fast twitch muscle fibers because they rely more on aerobic metabolism for energy production, which requires a higher number of mitochondria to generate ATP efficiently.
____ twitch muscle fibers are used for prolonged activity and have ___ mitochodria. Slow; many
Tetinus, Complete tetinus, and absolute summation
