The study of the response of the sciatic nerve and the neuromuscular to the Rana pipens was constructed by the Comparative Animal Physiology lab manual for both the nerve compound action potential (Lab five) and the neuromuscular junction (Lab six) (Norris, et al.,2016). In order to analyze the responses of the sciatic nerve and the gastrocnemius of a Rana pipens, one exercise was selected from Lab five and five exercises were selected from Lab six. Both lab five and Lab six had a study length of three weeks to be performed. Therefore, the first experiment focused on the nerve compound action potentials, while the second experiment focus on the neuromuscular junction. In the first experiment, the only exercise analyzed (Exercise one), was the determination of the threshold voltage and the relationship between stimulus intensity and compound action potentials(CAP). On the second experiment, five exercises were analyzed, these experiments focused on the stimulus intensity and strength of contraction, the effect of stretch on contractile force, the effect of paired pulses on contraction force(summation), muscle tetanus, and muscle and nerve fatigue. In lab five, exercise one, which focused on the determination of the threshold voltage and the relationship between stimulus and intensity and CAP of the Rana pipens the materials used were; a computer system, PowerLab with analog output, LabChart software, MLT012/B Nerve Bath, Frog Ringer’s solution, isolated
