Does the duration of the latent period change with different stimulus voltages how well did the results compare with your prediction no the latent period remained the same at the threshold stimulus, do sodium ions start to move into or out of the cell to bring about the membrane depolarization the threshold is the time at which the sodium ions start moving into the cell to bring about the. Does the duration of the latent period change with different stimulus voltages the latent period never changes no matter the force at the threshold stimulus, do sodium ions start to move into or out of the cell to bring about the membrane depolarization.

Give a definite answer please no fluff does the duration of the latent period change with different stimulus voltages how well did the results compare with your prediction. 1 how long is the latent period 278 msec 2 what occurs in the muscle during this apparent lack of activity ca++ is being released from the sacroplasmic reticulum and filament movement is taking up slack activity 3: investigating graded muscle response to increased stimulus intensity 1 use. Does the duration of the latent period change with different stimulus voltages how well did the results compare with your prediction you did not answer this question. 1) understand and define the following terms: muscle twitch, motor unit, latent period, contraction time, relaxation time, summation, tetany and fatigue 2) understand the ways muscle twitches can be manipulated, ie, increasing voltage, changing frequency, etc.

With different stimulus voltages, the duration of the latent period stays the same no matter what i though the latent period would change and my results proved otherwise 5. [physioex chapter 2 exercise 1] pex-02-01 will changes to the stimulus voltage alter the duration of the latent period your answer : b no, changing the stimulus voltage will not change the latent period duration does the duration of the latent period change with different stimulus voltages how well did the results compare with your. Muscle contractions have 3 different phases which include the latent period, contraction phase, and the relaxation phase (silverthorn, du, 2010) the latent period occurs between the start of an action potential and the beginning of a muscle contraction (stabler, etal, 2009. The latent period 3 what is the minimum voltage needed to generate active force in the skeletal muscle as the stimulus voltage increased, the resulting muscle tension _____ 27 skeletal muscle physiology 1. 1 reversible changes in twitch and tetanus contractions of isolated frog muscle fibres were produced by varying the duration and strength of a transversely applied dc stimulus 2 when the stimulus strength was at least 1 times threshold the peak force of the contraction elicited was reduced.

Does the duration of the latent period change with different stimulus voltages how well did the results compare with your prediction your answer: no, si se incrementa el estimulo, no cambia el tiempo de latencia. During the latent period of muscle contraction ca++ is being released from the sacroplasmic reticulum and filament movement is taking up slack does the duration of the latent period change with different stimulus voltages no sorry :( share to: the position of the stimulating electrode is what contributes tothe latent period the. This time interval is the latent period it exists because of all the things that must happen for the stimulus to reach the muscle and cause the myofilaments in the muscle fibers to begin sliding it exists because of all the things that must happen for the stimulus to reach the muscle and cause the myofilaments in the muscle fibers to begin. You correctly answered: c the latent period what occurs during the latent period will changes to the stimulus voltage alter the duration of the laten t period how does the trace at 130 stimuli/sec compare with the trace at 50 stimuli/sec no, changing the stimulus voltage will not change the latent period duration stop & think. Latent period is the length of time that it takes for a disease to develop.

Latent period • the sarcolemma and the t tubules depolarize subthreshold stimulus: a stimulus which does not evoke a visible response the number of motor units responding is not sufficient to cause visible movement study questions on the contraction of whole muscle: 1 (page 1. Does the duration of the latent period change with different stimulus voltages latent period remains the same at the threshold stimulus, do sodium ions start to move into or out of the cell to bring about the membrane depolarization. Increasing stimulus voltage causes more latent period is the time from stimulus are also stimulated by the “+” voltage change and begin to slowly open after inactivation of the nac, the delayed-opening of the action potential the wwwbiopaccom.

Yes00 0 changing the stimulus voltage will change the latent period duration proportionately the length of the muscle fiber is sliding into an optimal length the contractile period correct answer: c81 181 100 total force 00 length 75 75 75 75 75 75 active force 0. There is a delay, or latent period, of about 2 milliseconds (msec) between the onset of the stimulus and the onset of the twitch this is the time required for excitation, excitation-contraction coupling, and tensing of the series-elastic components of the muscle. A twitch is experiment results predict question: predict question: will changes to the stimulus voltage alter the duration of the latent period stop & think questions: what is the period of time that elapses between the generation of an action potential and the start of muscle tension development in a muscle fiber.

Keep increasing the stimulus until you observe a second response with a longer latent period (fig 97) click stop and record this threshold for the lateral giant fibers save your file to the desktop. The latent period of the skeletal muscle that was tested in this lab simulation was (exercise 2) 1 the latent period of the skeletal muscle that was tested in this lab simulation was a about 1 second b less than 1 msec c between 2-3 msec correct answer does the duration of the latent period change with different stimulus voltages. Yes, changing the stimulus voltage will change the latent period duration proportionately stop & think questions: what is the period of time that elapses between the generation of an action potential and the start of muscle tension development in a muscle fiber. The duration of the latent period: place one cursor line at the stimulus mark (in window 4) and the other on window 3 just before a contraction begins and read t2-t1 in upper left corner of screen this is the duration of the latent period in seconds.
