Alright I have the first part of this question I need the rest.
5.   Compare and contrast frequency-dependent wave summation with motor unit recruitment (previously observed by increasing the stimulus voltage). How are they similar? How was each achieved in the experiment? Explain how each is achieved in vivo.

Wave summation releases more calcium and increases the force of contraction by increasing the firing rate of motor neurons using one muscle fiber. Recruitment use multiple motor units, in order to increase the force of contraction. There is no added calcium ions as in wave summation. They usually occur together. wave summation can cause tetanus, while recruitment cannot. Summation was achieved by firing stimuli over and over before relaxtion of the muscle causing more force recruitment was achieved by rapid firing of stimuli to get max sooner.
