What are the 7 steps in sliding filament theory?
(1) Nerve stimulates membrane potential change (2) Transverse tubules conduct impulse to interior of muscle fibers (3) Calcium is released from terminal cisternae (4) Calcium binds to troponin (5) The bound troponin changes the shape of tropomyosin (6) Tropomyosin's shape change exposes the myosin binding sites on actin (7) Myosin bridges attach to actin to create muscular force
