How is the list below to be properly put in order to describe a muscular contraction?
1. Calcium causes exocytotic release of Acetylcholine into the synaptic gap; all this happens at an area called the neuromuscular junction
2. ATP is consumed which allows myosin to "pivot" the myosin head, which pulls actin toward it.
3. This process is repeated multiple times and is called the "sliding filament theory".
4. Myosin filaments perform "crossbridging".
5. Calcium is released and circulated throughout the muscle cell
6. The brain predicts the action necessary and decides which muscles and how many "motor units" are needed to perform that action.
7. Tropomyosin moves to reveal the active site of the F-Actin strand
8. Upon reception of a calcium ion, the Troponin complex becomes activated
9. Proteins embedded in the Sarcolemma receive enough of the ACH neurotransmitter to generate an electrical impulse.
10. The electrical impulse is perpetuated throughout the muscle fiber.
11. A nervouse impulse is generated in the brain and routed to the proper muscle
