Muscle twitch synonyms muscle twitch pronunciation muscle twitch translation english dictionary definition of muscle twitch. Muscle contraction types concentric the muscle shortens in length as it overcomes resistance.
Twitch summation or treppe is the addition of a second twitch resulting in greater tension and it results from stimulating the muscle before it has a chance to relax completely. Is a sudden involuntary movement of a muscle of extreme contraction then relaxation. The termination of muscle contraction is followed by muscle relaxation which is a.
