WebThis same concept is used in the Sliding Filament theory, only on a microscopic level. Within each sarcomere, centrally located myosin or thick filaments are stretched between the opposing fingers or actin filaments extending from each Z disc. There is a varying degree of overlap between the myosin filament and the surrounding actin filaments.
