Across
- 3. Sheet of fibrous connective tissue that encloses a muscle
- 5. Protein that interacts with actin (thin filament) to produce muscle contraction (thick filament)
- 7. Muscles that assist the movement of the prime mover
- 13. Chemical released by a neuron at a synapse that either stimulates or inhibits a reaction (contraction)
- 16. Muscle that opposes the prime mover
- 17. Structural and function component of a myofibril
- 18. Muscle pain
Down
- 1. Protein in muscle fiber that slides between filaments to produce a muscle contraction (thin filament); interacts with myosin (thick filament)
- 2. Muscle that provides a particular body movement
- 4. Sheet of connective tissue that attaches muscle to muscle
- 6. Contractile fiber in muscle cells
- 8. Connection between axon of a nerve and the myofibril. Where neurotransmitters are released to begin a contraction.
- 9. A motor neuron and its associated fibers
- 10. Stimulation level that must be exceeded to elicit and action potential to generate a muscle contraction
- 11. End of a muscle that attaches to a relatively immovable part
- 12. End of muscle attached to movable part
- 14. The force produced by a muscular contraction after a nerve impulse
- 15. Amount of oxygen required following physical exercise to react accumulated lactic acid to form glucose
