Across
  1. 3. property of muscle tissue, muscle fiber's ability to return to its original length when the tension of contraction is released
  2. 5. do not run the entire length of the muscle fiber, organized into repetitive groupings, including thin and thick
  3. 6. located at the end of each muscle where all the connective tissue merges, attaching the muscle to bone
  4. 9. flatlike appearance of tendons
  5. 10. complex motion that involves successive flexion, abduction, extension, and adduction
  6. 11. layer of connective tissue, innermost layer that surround and electrically insulates each muscle fiber
  7. 13. layer of connective tissue, surrounds individual fascicles
  8. 14. myosin, a motor protein that "walks" on thin filaments
  9. 15. actin and associated proteins
  10. 16. muscle fiber of the sarcoplasm extending entire length of the cell, have ability to shorten, resulting in contraction of the muscle and the production of motion
  11. 18. property of muscle tissue, ability of a muscle fiber to be stretched beyond its relaxed length
  12. 19. direction from median plane, anatomic position
  13. 20. layer of connective tissue, surrounds the entire muscle
  14. 21. number of skeletal muscles forming the muscular system
Down
  1. 1. movement of limb or other part towards the midline of the body or to another part
  2. 2. property of muscle tissue, stimuli can initiate electrical changes in the muscle fiber (cell) leading to contraction
  3. 4. property of muscle tissue, stimulation leads to contraction or shortening of the muscle fiber
  4. 7. layer of connective tissue, surrounds each muscle and separates muscles from each other
  5. 8. point of attachment to the bone that DOES NOT move
  6. 12. direction to median
  7. 17. diarthrotic ball-and-socket joint between head of humerus and glenoid cavity of scapula
