When a skeletal muscle is repetitively stimulated, twitches can overlap each other and result in a stronger muscle contraction than a stand-alone twitch this phenomenon is known as you correctly answered: c wave summation.
Because a skeletal muscle contraction requires metabolic energy, and in this experiment, there was an over- stimulation of the muscle, there was a depletion of this energy the depletion of the energy results in fatigue, causing the muscle to lose its ability to shorten and as a result, the muscle will fail.
Describe the effect of increasing stimulus voltage on isolated skeletal muscles from threshold voltage as the stimulus increases, so does the force of the contraction until it reaches maximum voltage.
Overview of skeletal muscle contraction skeletal muscle fibers are very large, elongated cells (fig 91) roughly 80% of the content of muscle physiology p3 muscle twitch parameters a twitch is a muscle contraction that occurs in the first few muscle fibers if stimulus is.
Latency is the interval between stimulus and a response to the stimulus, here meaning muscle contraction over this period, the action potential sweeps across the cell membrane of the muscle cell and the sarcoplasmic reticulum releases calcium ions.
