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