Across
- 5. bone building cells that synthesize and secret collagen fibers and other organic compounds
- 7. a remnant of the active epiphyseal plate; a sign that the bone stopped growing in length
- 8. type of fracture that the skin remains intact
- 9. complex bone shape that protects internal organs, examples are vertebrae and facial bones
- 13. area of growth in a long bone
- 14. the surface feature of bones vary considerably, depending on the function and location in the body
- 16. mature bone cells; main cells that exchange nutrients and waste with blood
- 17. hollow cylindrical space within diaphysis that contains fatty yellow bone marrow
- 18. hemopoietic tissue
- 20. help build bone by increasing absorption of calcium
Down
- 1. the tough membrane that surrounds the bone surface wherever cartilage is not present
- 2. between the diaphysis and epiphyses; location of the epiphyseal plate
- 3. process where the matrix is resorbed on one surface of a bone & deposited on another
- 4. as mineral salts are deposited in the collagen fiber framework, they crystallize and the tissue hardens
- 6. type of bone fracture that has several breaks and results in many small pieces between 2 large segments
- 10. thin layer of hyaline cartilage covering epiphysis where the bone forms an articulation joint with another bone; helps reduce friction and absorb shock
- 11. type of fracture that one end of the broken bone tears through the skin
- 12. the long, cylindrical main portion of the bone; the shaft
- 13. thin membrane lining the medullary cavity that contains bone-forming cells and connective tissue
- 15. triglyceride storage tissue
- 19. process of bone development; cartilage is replaced by bone through childhood
