Introduction
The experiment involved an examination of contractile responses of a skeletal muscle. This is completed using an electrical stimulus, a dissected motor nerve is stimulated to achieve the desired muscle contractions. Then the stimulation of the muscle itself was observed, allowing for a comparison of voltage (force) requirements.
This comparison of voltage’s is obtained by finding and recording the threshold and maximal for both the motor nerve and the muscle stimulus. The threshold records the minimal stimulus required to achieve a muscle contraction where as the maximal obtains the maximum contraction force that the muscle can produce. This demonstrates the effective purpose of the nervous system.
Complete tetanus is observed, causing the motor nerve and maximal stimulus voltage, increasing frequency until the muscle no longer shows a relaxation period. This can be observed when maximum contraction has been obtained in the muscle.
