Across
- 1. diseases that affect the muscles
- 3. gap between the neuron and motor end plate (ex: synaptic plate)
- 5. the functional unit inside of a muscle fiber
- 7. Muscle fiber + the motor neuron
- 8. smaller fibers within the muscle cell
- 10. membrane that surrounds the fascicles
- 12. effect of not having enough oxygen
- 14. causes contraction in the muscles
- 15. Enlargement of the muscle
- 16. excessive stretching and possible tearing of the muscle
- 17. The thick filament
- 18. The only voluntary muscle
- 20. A single muscle cell
- 21. muscles become small and weak due to disease
- 24. more and more fibers contract as the intensity of the stimulus increases
Down
- 2. where thick and thin filaments overlap
- 4. moveable end of the muscle
- 6. a sustained involuntary contraction
- 9. enzyme that breaks down ACH
- 11. muscles lose ability to contract after prolonged use
- 12. the immovable end of the muscle
- 13. energy source of muscle contraction
- 19. membrane that surrounds the muscle
- 22. The plasma membrane of muscle cells
- 23. the boundary between sarcomere
