Across
- 2. Cartilage plate located near the ends of bone. Bones become longer during childhood and adolescence because new cartilage is continually being added to the outer surface of the growth plates.
- 6. A mature bone cell
- 9. Connective tissue that forms the bony skeleton. Bone consists of a few living cells encased in a hard extracellular matrix of mineral salts.
- 10. A cell that resorbs or breaks down bone.
- 11. Cartilage forming cell. In the fetus, chondroblasts produce the hyaline cartilage that forms the rudimentary models of future bones.
- 13. Type of bone tissue characterized by thin, hard, interconnecting bony elements enclosing hollow spaces. Red blood cells are produced in the spaces between bony elements.
- 14. The junction or area of contact between two or more bones - articulation.
Down
- 1. Portion of the skeleton that forms the pectoral and pelvic girdles and the four extremities.
- 3. Portion of the skeleton that forms the main axis of the body, consisting of the skull, ribs, sternum, and backbone.
- 4. Dense fibrous connective tissue that connects bone to bone.
- 5. A cylindrical structure in bone composed of layers of living bone cells and hard extracellular material, arranged like the layers of an onion. In the center is a central canal through which nerves and blood vessels pass.
- 7. A bone forming cell.
- 8. Type of dense bone tissue found on the outer surface and shafts of bones.
- 11. White semi opaque flexible connective tissue
- 12. A cord of dense fibrous connective tissue attaching muscle to bone.
