What is the correct order of events for muscle contraction? Your

A) Nerve impulse is sent; Calcium channels open; Tropomyosin moves to expose binding sites on actin; Actin and myosin form linkages; Thin filaments are pulled toward center

B) Nerve impulse is sent; Tropomyosin moves to expose binding sites on actin; Calcium channels open; Actin and myosin form linkages; Thin filaments are pulled toward center

C) Nerve impulse is sent; Actin and myosin form linkages; Calcium channels open; Tropomyosin moves to expose binding sites on actin; Thin filaments are pulled toward center

D) Nerve impulse is sent; Calcium channels open; Actin and myosin form linkages; Tropomyosin moves to expose binding sites on actin; Thin filaments are pulled toward center
