Does latent period in mucles change with different stimulus/ increases voltage or does it remain the same. Physioex 2 activity 1 changes to the stimulus voltage alter the duration of the latent period no changing the stimulus voltage will not change the latent period. 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. Latent period of the muscle latent period, the stimulus applied to a muscle excites chemical changes which result in contraction but if the stimulus be very . For experiment one, the latent period was recorded in milliseconds and was compared to its corresponding stimulus voltage the time measurement (latent period) reflected the start of the flat line until it began to rise.

The maximal stimulus voltage is the point at which a further increase in stimulus voltage produces no further increase in the cap amplitude questions and answers q: why does the cap increase in size and duration with increasing stimulus strength. 1does the duration of the latent period change with different stimulus voltages explain 2injections of botox (botulinum toxin from the bacterium clostridium botulinum) are used in some cosmetic and medical procedures (eg, removing wrinkles). 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. Lab 9: conduction velocity of nerves if the stimulus voltage keep increasing the stimulus until you observe a second response with a longer latent period .

5does the duration of the latent period change with different stimulus voltages how well did the results compare with your prediction the latent period did not change with changes in stimulus voltage. 03/21/15 page 1 experiment results predict question: predict question: will changes to the stimulus voltage alter the duration of the latent period your answer : b 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 prediction each time the voltage was . Does the duration of the latent period change with different stimulus voltages no the latent did not change through all experiments this was the answer i chose.

Contraction of whole muscle latent period • the sarcolemma and the t tubules depolarize • in this animation you set the voltage, then record tension vs time. The latent period is caused by: time taken for the stimulus to travel along the nerve to the neuromuscular junction time taken for the impulse to cross the neuromuscular junction and to stimulate the muscle. Describe the latent period the period of time that elapses between the generation of an action potential in a muscle cell and the start of a muscle contraction although no force is generated, chemical changes occur intracellularly in preparation for contraction. 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 right corner of screen this is the duration of the latent period in seconds. Will changes to the stimulus voltage alter the duration of the latent period single stimulus activity 1: identifying the latent period 1 how long is the latent period .

Will changes to the stimulus voltage alter the duration of the latent period

You will notice that the multiple stimulus button changes to a stop stimulus button as soon as it is clicked after the trace has moved across the full screen and begins moving across the screen a second time, click the stop. 21 skeletal muscle physiology 1 as the stimulus voltage was increased in this activity, which of the following occurred the latent period 3 what is the . Will changes to the stimulus voltage alter the duration of the latent period no, changing the stimulus voltage will not change the latent period duration what occurs during the latent period of these isometric contractions. Does the duration of the latent period change with different stimulus voltages how would the relationship between the stimulus voltage and the amplitude of the response differ on a single .

Why doesn't a voltage change make a difference in the latent period of muscle twitch. 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. Show transcribed image text what changes to the stimulus voltage after the duration of the latent period explain during the latent period of a skeletal muscle twitch, there is an apparent lack of muscle activity. Does the duration of the latent period change with different stimulus voltages no the latent period did not change when diferent voltage of stimulus was applied at the threshold stimulus, do sodium ions start to move into or out of the cell to bring about the membrane depolarization.

Study 69 skeletal muscle physiology will changes to the stimulus voltage alter the duration of the latent period does the duration of the latent period . 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. Describe the effect of increasing stimulus voltage on isolated skeletal muscle specifically, what happened to the muscle force generated with stronger electrical stimulations and why did this change occur.
