Description: Examines the electrical triggering mechanism of muscle tissue. Shows the technique of electrically stimulating a single muscle fiber and points out that all muscle contractions are initiated by nerve impulses. Demonstrates the resting and firing potential of the muscle, and explains how a stimulus only triggers contraction, but does not maintain it.
