Question
Study the graphs below that were decribed in PhysioEx Exercise 2: Skeletal Muscle Physiology, Activity 4: Tetanus in Isolated Skeletal Muscle.
Tetanus occurs when a stimulus to a muscle is pplied frequently over a prolong period of time, the maximum possible muscle force from each stimulus will eventually reach a plateau.
In order for a muscle to go from 3 to 4 then from 5 to 6 you must
A- briefly stop stimulating the muscle to start up again
A- briefly stop stimulating the muscle to start up again
B- decrease the force C- increase the force D- increase the stimulus frequency E- increase the tension -Average tension (constant) Stimuli 1 4 6 Time (msec)Explanation / Answer
D. Increase the frequency of stimulus .. by doing this the muscle fibres will not get the relaxation time .. N they will progress to a plateau stage .that is stage 4.
