  1. 4. is made up of a motor neuron and the skeletal muscle fibers innervated by that motor neuron's axonal terminals.
  2. 7. also known as connection, is a protein that, in humans, is encoded by the TTN gene
  3. 10. can have causes that aren't due to underlying disease. Examples include low magnesium levels, muscle fatigue, or medication side effects.
  4. 13. refers to the condition in which muscles of the body remain semi-contracted for an extended period
  5. 15. a sheath of fibrous elastic tissue surrounding a muscle.
  6. 16. line formed between adjacent sarcomeres.
  7. 17. a wispy layer of areolar connective tissue that ensheaths each individual myocyte
  8. 19. a protein involved in muscle contraction. It is related to myosin and occurs together with troponin in the thin filaments of muscle tissue.
  9. 20. is the decline in ability of a muscle to generate force.
  10. 21. is the attachment site for the thick filaments.
  11. 23. a type of strength training in which the joint angle and muscle length do not change during contraction
  12. 25. Or resistance opposes movement
  13. 26. a muscle whose contraction moves a part of the body directly.
  14. 27. a structural unit of a myofibril in striated muscle, consisting of a dark band and the nearer half of each adjacent pale band.
  15. 28. a bundle of structures, such as nerve or muscle fibers or conducting vessels in plants.
  16. 29. the fine transparent tubular sheath that envelops the fibers of skeletal muscles.
  17. 31. a thin strip of flexible material used to encircle and bind one object or to hold a number of objects together
  18. 32. can be categorized into two types: slow-twitch (Type I) and fast-twitch (Type II). Type I muscle fibers are more efficient over long periods of time.
  19. 33. is an iron- and oxygen-binding protein found in the muscle tissue of vertebrates in general and in almost all mammals.
  20. 34. the fulcrum is a joint where a bone can move around the pivot point. The effort force is provided by muscles and is applied to the lever system at the point where the muscle's tendon attaches to the bone
Down
  1. 1. a protein of muscle that together with tropomyosin forms a regulatory protein complex controlling the interaction of actin and myosin and that when combined with calcium ions permits muscular contraction.
  2. 2. musical or vocal sound with reference to its pitch, quality, and strength.
  3. 3. are the filaments of myofibrils, constructed from proteins, principally myosin or actin.
  4. 5. the sheath of connective tissue surrounding a bundle of muscle fibers.
  5. 6. relating to or acting as an agonist.
  6. 8. muscle whose action is normally controlled by an individual's will; mainly skeletal muscle, composed of parallel bundles of striated, multinucleate fibers.
  7. 9. A protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion in other types of cells.
  8. 11. The act or process of inserting. Something inserted
  9. 12. The region of a striated muscle fibre that contains only thick (myosin) filaments.
  10. 14. There are two types, In a concentric contraction, the muscle tension rises to meet the resistance, then remains the same as the muscle shortens. In eccentric, the muscle lengthens due to the resistance being greater than the force the muscle is producing.
  11. 18. is the fixed attachment, while the insertion moves with contraction. The action, or particular movement of a muscle, can be described relative to the joint or the body part moved.
  12. 22. the process in which a muscle becomes or is made shorter and tighter.
  13. 24. are extensions of the cell membrane that penetrate into the centre of skeletal and cardiac muscle cells.
  14. 30. the cytoplasm of striated muscle cells.
