8. Neurons release acetylcholine, which binds to receptors on muscle cell membranes, stimulates an action potential in the muscle cell, and causes the muscle to contract. This statement is true false 9. Under muscle contraction, action potentials are carried along T tubules to the sarcoplasmic reticulum, where they cause the release of sodium ions. This statement is true false 10. In the sliding-filament model, the myosin molecules bend, causing the actin molecules to slide past. This statement is true
