  2. 5. Longitudinally, repeating functional unit of skeletal muscle
  3. 8. Cytoplasm of a muscle cell
  4. 9. Muscle contraction that lengthens the muscle as the tension is diminished
  5. 10. Loss of structural proteins from muscle fibers
  6. 12. Binds at a motor end-plate to trigger depolarization
