In a well-organized paragraph, develop a cohesive response to the following questions as you examine the responses modeled in the computer simulation. ● Name the factors that impact the ability for a skeletal muscle fiber to reach tetanus? o How do these factors affect tetanus production? (Greater or lesser causes what?) How does the length of a muscle fiber impact the total force that it develops upon stimulation?

The following is an oscilloscope tracing displaying the muscle twitch of an intact, viable frog skeletal muscle. The muscle was stimulated via electrodes placed on the muscle at time zero and again at 75 msec. Which of the following physiological phenomena does this demonstrate? Force 0 20 treppe fatigue fused tetanus wave summation 120 Time (msec) 2015 a 180 200

Please answer all of this following questions in your own words, thank you.  Q1: Which muscles form the quadriceps? How do they function together? Q2: studied the steps of skeletal muscle contraction (sliding filament mechanism). Briefly outline the steps of the sliding filament model of muscle contraction. just mention what is happening with each of the "filaments." Q3: What would be the effect on the muscle if acetylcholinesterase was not present? (8)

Which of the following are part of the muscle contraction process?(More than one answer may be correct, please aid in answering) Question 5 options:   ATP binds and detaches myosin head from actin   GTP is hydrolyzed to GDP + P   Acetylcholine released into neuromuscular junction by motor neurons   Prolactin stimulates the reuptake of ATP.   Ca2+ binds to troponin which moves tropomyosin away from actin
