Across
  1. 5. – Process of blood cell formation that occurs in red bone marrow.
  2. 8. cartilage – Hyaline cartilage that covers the ends of bones in synovial joints.
  3. 10. – Cell that will form/build bone tissue.
  4. 13. bone – Bone that consists of bars and plates separated by irregular spaces; also called cancellous bone.
  5. 15. – The formation of bone tissue.
  6. 18. – Mature bone cell.
  7. 19. system – The organ system that includes the bones, and the ligaments and cartilages that hold them together.
  8. 21. skeleton – Upright portion of the skeleton (skull, vertebral column, and thoracic cage) that supports the head, neck, and trunk.
  9. 22. – Branching bony plate that separates irregular spaces within spongy bone.
  10. 24. – Shaft of a long bone.
  11. 25. – Small chamber or cavity.
  12. 26. bone – Dense bone tissue in which cells are organized in osteons without apparent spaces; cortical bone.
Down
  1. 1. – Dense connective tissue covering the surface of a bone.
  2. 2. – Opening or passageway through a bone, usually allowing nerves and blood vessels to pass.
  3. 3. – Thin layer of cells lining the medullary cavity and spaces of spongy bone.
  4. 4. plate – Cartilaginous layer between the epiphysis and diaphysis of a long bone that grows, lengthening the bone.
  5. 6. – Expanded end of a long bone that forms a joint with another bone.
  6. 7. – Soft connective tissue that fills the internal spaces in bones (can be red or yellow).
  7. 9. bones – Bones that have a variety of shapes and are mostly connected to several other bones.
  8. 11. bone – A bone that has roughly equal length and width.
  9. 12. bone – A bone that has a long longitudinal axis and an expanded end.
  10. 14. – Cell that breaks down bone tissue.
  11. 16. bone – A bone that is platelike in structure with a broad surface.
  12. 17. – Microscopic canal that connects lacunae of bone tissue.
  13. 20. cavity – Tubelike hollow space inside the diaphysis of a long bone that contains marrow.
  14. 23. skeleton – Portion of the skeleton consisting of the upper and lower limbs and the shoulder and pelvic girdles.
