Across
- 3. blood cell formation; occurs within red bone marrow
- 9. 2nd cervical vertebrae; contains the dens
- 11. hyaline cartilage that covers the epiphysis of long bones
- 12. soft spots in a baby's skull; permits movement during the birthing process
- 14. bone breaking/resorbing cell
- 16. end of a long bone; filled with spongy bone with red bone marrow
- 17. layer of bone tissue that has many small spaces and is found just inside the layer of compact bone and the epiphysis; contains red bone marrow
- 20. type of bone that develops between sheets of cartilage; bones of the skull
- 22. small cavities in bone that contain osteocytes
- 23. bones of the limbs and limb girdles that are attached to the axial skeleton
- 24. under the periosteum, smooth and very hard; found in the diaphysis
- 26. most common type of bone; develops from hyaline cartilage and ossification centers
Down
- 1. cartilaginous layer within the epiphysis of a long bone that grows
- 2. shaft of long bone, composed of compact bone
- 4. mature bone cell
- 5. portion of the skeletal system that consists of the skull, hyoid, rib cage, and vertebral column
- 6. middle of the osteon, allows for passage of blood vessels, lymphatic vessels, and nerves; every osteon has one central canal
- 7. 1st cervical vertebrae; articulates with the occipital bone
- 8. basic structural and functional unit of compact bone
- 10. type of fibrous joint; Do NOT move at all; found in the skull
- 13. thin,dense membrane that covers the diaphysis and contains nerves and blood vessels that nourish the bone.
- 15. place where 2 bones meet
- 18. concentric rings of hard, calcified matrix
- 19. bone-forming cells that secrete the bone matrix; responsible for bone growth
- 21. hairlike canals that connect lacunae to each other and the central canal
- 25. within the shaft of the long bones filled with yellow bone marrow that stores fat
