Across
- 1. also known as the rib cage, is the bony structure that protects the heart and lungs
- 3. hips, thighs, legs, ankles and feet
- 4. makes body movement possible and protects the organs of digestion, excretion and reproduction including upper and lower extremities
- 6. a joint allowing movement in two planes: front to back and side to side; wrist joints
- 7. created where two bones articulate to permit a variety of motions, 6 types
- 9. consisting of inflexible layers of dense connective tissue, holding bones tightly together
- 12. forms the lining of synovial joints and secretes synovial fluid
- 13. three pair of ribs attaching anteriorly to cartilage that connects them to the sternum
- 14. the process of bone formation
- 17. the 12 pairs of ribs attaching posteriorly to the thoracic vertebrae
- 18. first seven pair of ribs attaching anteriorly to the sternum
- 20. made up of the 8 bones that protect the brain
- 21. connects bones to bones
- 23. body parts that extend from the main body or trunk, like arms and legs
- 25. also known as the jawbone, is the only movable bone of the skull
- 26. 80 bones of the head and body, protecting the nervous, respiratory and circulatory systems
- 27. allows bones to rotate around a single axis; atlas and axis
- 28. saddle-shaped joint surface permitting movements in all directions except axial rotation; thumb joint
- 30. the soft, spongy tissue that is in the medullary cavities (centers) of bones
- 31. shoulders, arms, forearms, wrists and hands
- 32. cushions areas subject to friction during movement
Down
- 2. allow only slight movement and consist of bones connected entirely by cartilage; ribs
- 5. last two pair of ribs that only attach posteriorly to the vertebrae and are not attached anteriorly
- 8. (plane joint)allow bones to slide past each other in a single plane; intercarpal joints between the wrist
- 10. lubricant that makes smooth joint movements possible
- 11. a joint that allow movement primarily in one direction or plane; knees and elbows
- 14. forms the back part of the skull and the base of the cranium
- 15. creates a smooth surface for motion within the joints and protects the ends of the bones
- 16. work with the muscles to make a variety of movement possible
- 19. a joint in which a ball moves within a socket so as to allow rotary motion in every direction; shoulder, hip
- 22. act as the framework for the body, protects internal organs and stores calcium
- 24. consists of the 8 bones of the cranium, 14 of the face and 6 of the inner ear
- 29. an opening in a bone through which blood vessels, nerves and ligaments pass
