Skeletal System

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

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
