    Design an experiment to test the following hypothesis: Muscle A has the same number of motor units as muscle B. Assume you could stimulate the nerves that innervate skeletal muscles with an electronic stimulator and monitor the tension produced by the muscles.

    Solution Preview

    Since motor units are the motor nerve and all of the muscle fibers that this one nerve enervates, and motor units are therefore an all-or-nothing contraction unit, if one muscle has fewer motor units than another that muscle would produce an overall smaller tension than the other.

    So you experiment would look something like this: ...

    Solution Summary

    This solution discusses a possible experimental design to test the given hypothesis: Muscle A has the same number of motor units as muscle B.
