Following tetanizing stimulus was to a muscle, there is a constant contraction. This is due to
Tetanization: as the frequency of the stimulus increases to a critical level the successive contractions become so rapid that whole muscle contraction becomes smooth and contineous This is called tetanization and frequency is tetanizing frequency Ref:Guyton and Hall textbook of medical physiology 12th edition,page number:97
General physiology
Recruitment phenomenon
At high stimulus frequency all muscle fibers are contacting
Contraction of different muscle fibers at different places
All of the above
At high stimulus frequency all muscle fibers are contacting
