What is stimulus voltage?

What is stimulus voltage?

Increasing the stimulus voltage on isolated skeletal muscle increases the amount of active force produced by the muscle. The potential then reaches a plateau which is called the maximal voltage where no matter how many muscle fibers are activated, the amount of force produced remains the same.

What is maximal stimulus voltage?

Maximal stimulation is the voltage or current at which the isometric twitch force produced is maximal. Supramaximal stimulation is the voltage or current at which the isometric twitch force is maximal plus ~15% to ensure that all fibers are activated simultaneously.

How did the muscle respond as you increase the stimulus voltage?

As the intensity (voltage) of the stimulus is increased above the threshold, more and more fibers are stimulated and the response becomes greater and greater. This stimulus, called the maximal stimulus marks the point where all of the fibers in the muscle are stimulated and responding all-or-none.

Will changes to the stimulus voltage?

Will changes to the stimulus voltage alter the duration of the latent period? No, changes to the stimulus intensity will not change the duration of the latent period. The latent period is a chemical event initiated by the stimulus regardless of its intensity.

What is the difference between stimulus intensity and frequency?

1. What is the difference between stimulus intensity and stimulus frequency? The stimulus intensity is the electrical changes that relate to the action potential. The Page 2 Copyright © 2014 Pearson Education, Inc. frequency is the number of action potentials per minute.

What is the difference between stimulus intensity and stimulus frequency?

Does the duration of latent period change with different stimulus voltages?

The latent period did not change with changes in stimulus voltage.

Does latent period change with different stimulus voltage?

What is the relationship between stimulus frequency and muscle force?

The force–frequency relationship presents the amount of force a muscle can produce as a function of the frequency of activation. During repetitive muscular contractions, fatigue and potentiation may both impact the resultant contractile response.

When the stimulus frequency reaches a value beyond which no further?

When the stimulus frequency reaches a value beyond which no further increases in force are generated by the muscle, the muscle has reached its You correctly answered: a. maximal tetanic tension.… show more content… 1.

How is the threshold stimulus voltage determined in compound action potential?

The threshold stimulus voltage is determined by raising and lowering the stimulus voltage a little to find the voltage at which the CAP is just discernible. The maximal stimulus voltage is the point at which a further increase in stimulus voltage produces no further increase in the CAP amplitude.

What happens to active force as stimulus voltage increases?

Predict: As the stimulus voltage is increased from 1.0 volt up to 10 volts, what will happen to the amount of active force generated with each stimulus? The active force will first increase and then plateau at some maximal value as the stimulus voltage increases. Motor unit recruitment refers to:

Which is the best definition of the word stimuli?

noun, plural stim·u·li [stim-yuh-lahy] /ˈstɪm yəˌlaɪ/. something that incites to action or exertion or quickens action, feeling, thought, etc.: The approval of others is a potent stimulus. something that stimulates or acts as an incentive

What happens when the threshold voltage is increased?

threshold voltage Predict: As the stimulus voltage is increased from 1.0 volt up to 10 volts, what will happen to the amount of active force generated with each stimulus? The active force will first increase and then plateau at some maximal value as the stimulus voltage increases. Motor unit recruitment refers to:
