The individual make and break shocks are repeated so quickly that a continuous contraction is obtained. muscle during a period of ten seconds. Compare this curve with the one obtained previously. Since the tetanic contraction is the result of the summation and fusion of simple twitches, it is much higher and longer than a twitch. If long continued, the height of the curve de- clines slowly, owing to Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Burton-Opitz, Russell, b. 1875.
