Passage II (Questions 15-20) In a muscle experiment, the optimal length of an isolated frog gastrocnemius muscle was not known. To resolve the problem, the length of stretch of the muscle was varied five times in increments of 2 mm. With each stretch, a stimulation was applied to the sciatic so as to produce a muscle twitch. Figure I depicts results from the experiment. Table I is an incomplete table that depicts different types of tensions from the muscle experiment....

1. Explain the steps involved in muscle contraction starting from stimulation of the sciatic nerve (somatic motor neuron) to contraction of the muscle fibers within the gastrocnemius. Be sure to include any movements of ions, neurotransmitters, myofilaments and other relevant structures/particles in your answer. (3 pts) 2. Why do we see a graded response (tension increasing) in single muscle twitch when increasing the voltage (strength) of the stimulus that is applied? Was there a point at which maximal tension was...
