Example of tetanic contraction

WebThe tetanic contractions of motor units are the effect of repetitive activations of muscle fibers and the summation of responses to successive stimuli. However, these responses are not identical. Originally, it was revealed by calculating the difference between the contraction evoked by n+1 stimuli and the contraction evoked by n stimuli (Stein and … WebTetanic force was measured by admin- istering a 300-ms pulse train at increasing fre- quencies (50 Hz, 80 Hz, 100 Hz, 120 Hz, and 140 Hz) until maximal tetanic isometric …

Tetanic contraction synonyms, Tetanic contraction pronunciation, Tetanic contraction translation, English dictionary definition of Tetanic … A tetanic contraction (also called tetanized state, tetanus, or physiologic tetanus, the latter to differentiate from the disease called tetanus) is a sustained muscle contraction evoked when the motor nerve that innervates a skeletal muscle emits action potentials at a very high rate. During this state, a motor unit has been maximally stimulated by its motor neuron and remains that way for some time. This occurs when a muscle's motor unit is stimulated by multiple impulses at a suffic… trx basics https://xquisitemas.com

WebDec 1, 1997 · Peak torque of the tetanic contraction and the decrease in torque during the 7-s tetanus were determined. The peak-to-peak amplitude of the muscle compound action potential (M wave) associated with each twitch response was measured. ... In this example, tetanic torque decreased 13% during the 7-s tetanus. Peak torque potentiated by 50% ... WebQuestion 9. The force of a tetanic contraction is greater than that of a twitch contraction because: a) More acetylcholine is released at the neuromuscular junction per nerve impulse. b) More Ca2+ is released in a tetanic contraction. c) The muscle action potentials travel faster along the transverse tubules.
