During contraction, myosin heads bind to actin molecules of the. thin filaments. Flexing of the myosin heads pulls the thin filaments over the thick. filaments - shortening the sarcomere. Muscle contraction requires.
During movement, the muscle that is contracted is the agonist muscle and the opposing muscle is the antagonist, that returns the agonist muscle back to its relaxed state.7 people found this useful.
