Thick filament - Study guides, Class notes & Summaries

Components of myofibrils myosin- thick filament, with head , rsponsible for splitting ATP providing energy for the power stroke to grab onto the actin actin- thin filament, double helix troponin in actinbinds with Ca2+ from SR, exposes binding site on myosin to form cross bridges Crircular muscle structure arranged in a concentric ring Convergent muscle structure broad origin leading to a fan shaped muscle, looks similar to a brush or duster Parallell or longitudinal muscle structu...
