PAM1HSF Week 6 Muscle
Across
- 2. Plasma membrane of a skeletal muscle fiber
- 5. Longitudinally, repeating functional unit of skeletal muscle
- 8. Cytoplasm of a muscle cell
- 9. Muscle contraction that lengthens the muscle as the tension is diminished
- 10. Loss of structural proteins from muscle fibers
- 12. Binds at a motor end-plate to trigger depolarization
- 14. Muscle contraction that involves changes in muscle length
- 15. Connective tissue that bundles skeletal muscle fibers into fascicles within a skeletal muscle
- 17. Muscle contraction that occurs with no change in muscle length
- 18. Long, cylindrical organelle that runs parallel within the muscle fiber and contains the sarcomeres
Down
- 1. Bundle of muscle fibers within a skeletal muscle
- 3. Loose connective tissue covering each muscle fiber in a skeletal muscle
- 4. Makes up most of the thin myofilaments in a sarcomere
- 6. Makes up most of the thick cylindrical myofilament within a sarcomere muscle fiber
- 7. Muscle contraction that shortens the muscle to move a load
- 11. Force generated by the contraction of the muscle
- 13. Addition of structural proteins to muscle fibers
- 16. Motor neuron and the group of muscle fibers it innervates
