...Michael M. DuVall; Azim Jinha; Gudrun Schappacher-Tilp; Timothy R. Leonard; Walter Herzog ABSTRACT Since the 1950s, muscle contraction has been explained using a two-filament system in which actin and myosin exclusively dictate active force in muscle sarcomeres. Decades later, a third filament...
