Across
- 1. dense osseous tissue that can withstand compressive forces
- 6. uncalcified bone matrix secreted by osteoblasts
- 7. (singular = canaliculus) channels within the bone matrix that house one of an osteocyte’s many cytoplasmic extensions that it uses to communicate and receive nutrients
- 8. hollow region of the diaphysis; filled with yellow marrow
- 10. undifferentiated cell with high mitotic activity; the only bone cells that divide; they differentiate and develop into osteoblasts
- 12. thin layer of cartilage covering an epiphysis; reduces friction and acts as a shock absorber
- 15. process by which bone forms directly from mesenchymal tissue
- 16. cell responsible for forming new bone
Down
- 2. (also, Volkmann’s canal) channel that branches off from the central canal and houses vessels and nerves that extend to the periosteum and endosteum
- 3. (also, growth plate) sheet of hyaline cartilage in the metaphysis of an immature bone; replaced by bone tissue as the organ grows in length
- 4. cell responsible for resorbing bone
- 5. process in which bone forms by replacing hyaline cartilage
- 6. cluster of osteoblasts found in the early stages of intramembranous ossification
- 9. production of blood cells, which occurs in the red marrow of the bones
- 11. longitudinal channel in the center of each osteon; contains blood vessels, nerves, and lymphatic vessels; also known as the Haversian canal
- 13. (also, cancellous bone) trabeculated osseous tissue that supports shifts in weight distribution
- 14. layer of spongy bone, that is sandwiched between the two layers of compact bone found in flat bones
