| Sarcolemma | Cell's membrane |
| Calcium | Stored in sarcoplasmic reticulum |
| Releases myosin heads from actin | ATP |
| Carries action potential into cell | T-tubule |
| Blocks binding sites on actin | Tropomyosin |
| Motor neurotransmitter | Acetylcholine |
| Source of neurotransmitter | Motor neuron |
| Binds with neurotransmitters | Motor end plate |
| Membrane charge at rest | Resting potential |
| Calcium binds to this protein | Troponin |
| When these attach to actin, contraction occurs | Myosin heads |
| The range of electrical charge in a membrane is this | Membrane potential |
| The gap between muscle and nerve cells | Synapse |
| The "T" in T-tubule means this | Transverse |
