Primary myofilaments of direct flight muscle fibers are hexagonally arranged, are surrounded by six secondary myofilaments, and are composed of two sub-unit-fibrils, 90–120 Å in diameter, at mid-sarcomere levels. Primary myofilaments are resolvable into electron-densities 15–25 Å in diameter, which number 3–4 in each sub-fibril at mid-sarcomere levels, and… (More)
