4) You set up an experiment using an isolated mouse muscle-nerve preparation. a. Draw the force traces (used to measure the force of contraction using a force transducer) you would expect to get if you stimulated the nerve at 3 different lengths: 1) slack, 2) the normal length of the muscle in the body, and 3) stretched past a length the muscle could ever experience in a mouse. If the force traces are different explain why. (Hint: refer back to the length-tension relationship) b. Draw the nerve signals you would record from a Group Ia muscle spindle afferent at each of those 3 lengths. If the 3 conditions are different explain why. (Hint: refer back to the function of the muscle spindle
