Put these events in the correct chronological sequence. 1. end plate potentials trigger action potentials 2. transverse tubules convey potentials into the interior of the cell 3. acetylcholine binds to receptors on the motor end plate 4. high affinity binding sites on actin are uncovered allowing myosin to strongly bind and perform a power stoke 5. calcium is released from the sarcoplasmic reticulum 6. chemically gated ion channels open, causing depolarization 7. calcium binds to troponin-c affecting tropomyosin
