Across
- 5. Junction Where a nerve and muscle fiber come together
- 6. Vesicles Where neurotransmitters are stored
- 9. Muscles become small and weak due to disease
- 10. Fatigue Muscle loses ability to contract
- 13. The smaller fibers in a muscle cell
- 14. The neurotransmitters that cross the synaptic Gap and cause muscle contractions
- 15. Make our heart beat
- 17. Enzyme that breaks down ACH
- 19. Enlargement of a muscle
- 20. Is not under conscious control
- 21. Cramp A sustained involuntary contraction
Down
- 1. Under conscious control
- 2. End Plate Folded area of the carcolemma
- 3. Fascicles are surrounded by a membrane called this
- 4. response Fibers do not partially contract, they either do or don't
- 6. Muscle Contains actin and myosin
- 7. Muscle Main tissues of the walls of the heart
- 8. Fiber A single muscle cell is called this
- 11. Unit The muscle fiber and motor neuron
- 12. Stimulus The minimal amount of stimulus required to cause a contraction
- 16. Gap between the neuron and motor end plate
- 18. Muscle Found in walls of hollow organs
