Across
- 3. The repeating unit of muscle contraction in striated muscle
- 5. Division of the ANS that promotes digestion and rest
- 9. Protein that binds calcium to uncover actin binding sites
- 12. A single motor neuron and all the muscle fibers it innervates
- 14. The membrane potential becomes less negative as sodium enters the cell
- 15. Division of the autonomic nervous system activated during stress
Down
- 1. Enzyme that breaks down acetylcholine in the synaptic cleft
- 2. Type of conduction where action potentials jump between nodes
- 4. Insulating layer that speeds up action potential conduction
- 6. Minimum membrane potential needed to trigger an action potential
- 7. Blocks ACh release by preventing vesicle fusion at the presynaptic membrane
- 8. Thick filament that pulls actin during muscle contraction
- 10. Type of ACh receptor located on skeletal muscle fibers
- 11. Receptor that monitors muscle tension and prevents excessive force
- 13. Neurotransmitter released at all neuromuscular junctions
