active muscles require decreasing degrees of succeeding stimuli to elicit maximal contractions Exercise 3: Wave Summation A. Explain why wave summation occurs. Wave summation occurs when a second stimulus is applied before the first stimulus is lost. The two responses combine to produce a greater muscle tension than produced be a single response. B. Can summation go on infinitely? Why or why not? If the stimulation continues and muscle never reaches its relaxation period

What .is the role of acetylcholine in a skeletal muscle contraction? Skeletal muscle fiber-Skeletal muscle fibers are the individual cells that are bound together in fascicles. Many fascicles are bound together to make a muscle Motor unit-A motor unit consists of a motor neuron and all of the muscle

continued to follow this trace continuously. 7. What part of the trace shows the refractory period? The atrial contraction is the part of the trace that shows the refractory period. 8. Does summation occur? No‚ summation does not occur. 9. Why is it important that summation not occur in heart muscle? Summation would increase the Heart muscle contractions which would lead to a heart attack. Activity 2: Vagus Nerve Stimulation 1. Describe the effect of the vagus nerve stimulation on the heartbeat

Introduction Jan Swammerdam‚ who demonstrated that an isolated frog muscle could be made to contract when the sciatic nerve was irritated with a metal object‚ conducted the first muscle experiments between 1661 and 1665. Later‚ between 1737-1798 Luigi Galvani determined that frog muscle responded to electrical currents. The kymograph‚ which was invented in the late 1840’s lead to the revolution of experimental physiology because it enabled muscle contractions to be analyzed and recorded. The muscle

The prosecutor is completely victorious. His summation in the trial was strong‚ intense‚ and exposed how devoted he was to justice. In a part of his summation‚ he said‚ “But here in this court the wholly negative virtue of tolerance must give way to the sterner but loftier virtue of justice.
