Across
  1. 3. fine motor control
  2. 6. typically attach to projections on bone
  3. 7. can be stimulated to contract by chemical or electrical signals
  4. 8. connective tissue joining muscle to bone; usually rope-like
  5. 9. anchor muscle to bones or skin (or other muscles)
  6. 10. multiple insertions
  7. 13. is attached to tendons
  8. 16. connective tissue surrounding bundles of muscle fibers
  9. 18. moveable skeletal element/ onlimb: usually distal
  10. 19. tissue this tissue contributes to tendon and continues to mesh with periosteum and continues into bone
  11. 23. connective tissue surrounding each muscle fiber
  12. 25. can contract, generate tension (=pulling force)
  13. 26. connection between neuron and skeletal muscle fiber, muscle fiber recieves neurotransmitter(acetylcholine) from neuron to stimulate contraction
  14. 27. made of long cylindrical cells called myofibers, multinucleated and striated, attached to skeletal elements or skin, and generates conscious/voluntary actions
Down
  1. 1. greater strength
  2. 2. sheet-like tendon
  3. 4. gross motor control
  4. 5. stationary skeletal element; anchors muscle/ on limb: usually proximal
  5. 11. greater speed
  6. 12. located in the heart, pressurizes blood to circulate it, cells are branched and connected end to end, it is striated, regulated autonomically (involuntary)
  7. 14. unit all muscle fibers innervated by single neuron; contracts as unit
  8. 15. multiple origins
  9. 17. dense connective tissue surrounding muscle
  10. 20. returns to resting length after being stretched or contracting
  11. 21. innervated by somatic motor neurons
  12. 22. found in many organs, regulated autonomically(involuntary), cells are highly stretchable and resistant to fatigue, unstriated
  13. 23. can be stretched beyond resting length without being damaged
  14. 24. generates tension by a pulling force
