Unformatted text preview: +2 in between each twitch. This phenomenon is known as temporal or wave summation and at the higher end of the mid-level range, incomplete tetanus. Higher frequencies of stimulation allows no time to relax between stimuli so twitches fuse into a smooth prolonged contraction called complete tetanus and gives rise to normal smooth muscular movements. Isometric and Isotonic Contractions The contraction of muscles results in increasing tension, but may not always result in movement of a body part. Isometric muscle contraction develops tension without changing the length of a muscle while isotonic muscle contractions change the length of a muscle without changing tension....
