Twitch, Summation and Tetanus in Skeletal Muscle Contraction:
Twitch is a contraction of a single muscle fiber by a single stimulus. It is the smallest unit of muscle contraction. Frequency summation is adding up multiple twitches of same muscle fibers by stimulating it at higher frequency. In frequency summation, tetanus is seen when individual twitches fuses tougher and they are not distinguishable from one another. Multiple fiber summation is stimulating multiple fibers simultaneously. At weak stimulus, smaller motor units are activated, and with increasing strength of stimulus, large motor units are recruited. And different motor units are activated asynchronously.
