List all the steps for a muscle contraction
1. Action potential arrives in nerve to send signals to the muscle.
2. Acetylcholine is released into the synapse and binds to the motor end plate.
3. Calcium gets released within the muscle.
4. Troponin is released in response.
5. Tropomyosin causes actin to rotate, opening the binding site.
6. Myosin head binds to actin and produces a "power stroke" motion.
7. Actin is pulled toward the center of the sarcomere and 'slides' across overtop the myosin
