When а mоtоr neurоn is depolаrized, the аction potential cause release of the [A] neurotransmitter into the synapse between the neuron and muscle fiber. When that neurotransmitter binds to receptors on the muscle fiber, [B] ions enter T tubules and the muscle fiber depolarizes. This opens a voltage gated [C] channel on the sarcoplasmic reticulum and this ion rushes into the sarcoplasm. There it binds to the protein [D] causing the protein [E] to move. Now, cross-bridges can form, and a contraction is triggered. Word bank – just use the number associated with each choice. 1 = Calcium. 2 = Potassium. 3 = Sodium. 4. Titin. 5= Tropomyosin. 6 = Troponin 7 = Nebulin 8 = Acetylcholine. 9 = Dopamine
