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