Webb1. A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles Muscle contraction begins when the nervous system generates a signal. … WebbATP and Muscle Contraction The motion of muscle shortening occurs as myosin heads bind to actin and pull the actin inwards. This action requires energy, which is provided by ATP. Myosin binds to actin at a binding site on the globular actin protein.
