Skeletal System

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

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
