Skeletal System
Across
- 4. Ribs 8-12 with articulate indirectly to the sternum or not at all
- 5. Red blood cell production
- 8. Dense bone that looks smooth and homogenous
- 9. Broken bone
- 15. joint Joint that provides no movement
- 18. Soft bones caused by lack of vitamin D, calcium, or phosphorus
- 22. Refers to the shoulder region
- 23. The last two pair of false ribs which do not articulate to the sternum
- 24. End of a long bone; composed mostly of spongy bone
- 25. 5 vertebrae in the lower back; largest vertebrae
- 26. Cavities in which bone cells can be found within the bone matrix
- 28. Spaces between bones in an infant skull
- 30. Complex consisting of a Haversian canal and the lamellae surrounding it
- 31. Marking left on the bone from growth at the epiphyseal plate
- 33. Ribs 1-7 which articulate directly to the sternum by cartilage
- 34. Site of fat storage in medullary cavity of long bones
- 35. A joint; where two bones meet
- 37. Cartilage that covers the epiphyses for smooth movement
- 38. Refers to the hip region
- 39. Tiny canals that radiate outward from the Haversian canal to lacunae to supply the bone cells with nutrients.
- 40. Bone-destroying cells
Down
- 1. Mature bone cells
- 2. Site of hematopoiesis in the cavities of spongy bone
- 3. Inflammation of the joints that occurs with aging
- 6. The first vertebra, C1; allows you to nod your head
- 7. Composed of bones that make up the limbs and girdles which attach limbs to the axial skeleton
- 10. Second vertebra in the neck, C2; allows rotation of the head
- 11. Bone that is composed of small pieces of bone and lots of open space
- 12. Process of bone formation from cartilage
- 13. Bone-building cells
- 14. 12 vertebrae in the chest; attached to ribs
- 16. joint Joint that is slightly moveable
- 17. Shaft of a long bone; composed of compact bone
- 19. Abnormal curvature of the spine
- 20. joint Type of joint that allows the most movement; bones are separated by a cavity filled with synovial fluid
- 21. Weakening of bone that occurs with aging
- 27. Composed of bones that form the longitudinal axis of the body from the skull to the end of the vertebral column
- 29. Concentric circles or rings of lacunae found in bone tissue
- 32. Canals in bone tissue that carry blood vessels and nerves
- 36. 7 vertebrae in the neck
