Across
- 1. a movement that increases the distance between two body parts
- 4. has two types; threadlike protein
- 6. contractile protein found in thin filaments
- 8. no striation and involuntary movement
- 10. occurs in the mitochondria and involves the a series of metabolic pathways; uses oxygen
- 14. allows whistling
- 15. combination of movements; seen in ball-and-socket joints
- 17. movement that brings bones closer together
- 19. one neuron and all the skeletal muscle cells
- 21. the gap between the nerve endings
- 22. a weak muscle that inserts into the distal forearm
- 24. produced during an anaerobic process; glycolysis
- 26. helps by reducing unwanted movement
- 28. movement around a longitudal axis
Down
- 1. muscle used to rotate the trunk
- 2. muscle allows lift of eyebrow
- 3. continuous partial contractions; result of different motor units
- 5. muscle used during swimming; used for powerful down stroke
- 7. movement of thumb to finger
- 9. muscle that stabilize the scapula
- 10. moving a limb away from the midline
- 11. allows squinting
- 12. muscle used to flex the vertebral column
- 13. allows kissing
- 16. found only in the heart
- 18. elongated skeletal and smooth muscle cells
- 20. fibers have stripes
- 23. moving a limb towards the body midline
- 25. fan-shaped muscle; pectoralis major
