Across
- 4. an opening, hole, or passage, especially in a bone
- 7. the shaft or central part of a long bone
- 9. articulation that permits free movement, a freely movable joint (also called synovial joint)
- 12. a cavity or depression, especially in bone
- 15. the formation of bone
- 16. a lifelong process where mature bone tissue is removed from the skeleton and new bone tissue is formed
- 18. an anatomical feature of the infant human skull comprising any of the soft membranous gaps (sutures) between the cranial bones that make up the calvaria of a fetus or an infant
- 19. a bone cell, formed when an osteoblast becomes embedded in the matrix it has secreted
- 20. system the cylindrical, column-like structures in compact bones, it consists of microscopic cylindrical structures oriented parallel to the long axis of a bone
Down
- 1. a type of continuous, slightly movable joint
- 2. microscopic canals between the lacunae of ossified bone, its radiating processes of the osteocytes (called filo podia) project into these canals; these cytoplasmic processes are joined together by gap junctions
- 3. the state of being jointed
- 5. a cell that has secreted the matrix of cartilage and become embedded in it
- 6. a thin layer, membrane, scale, or plate like tissue or part, especially in bone tissue
- 8. plate a hyaline cartilage plate in the metaphysis at each end of a long bone, its plate is found in children and adolescents; in adults who have stopped growing, the plate is replaced by an epiphyseal line
- 10. the production of blood cells and platelets, which occurs in the bone marrow
- 11. a fluid-filled sac or saclike cavity, especially one countering friction at a joint
- 13. the absorption into the circulation of cells or tissue
- 14. a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints
- 17. a cell that secretes the matrix for bone formation
- 21. membrane the soft tissue found between the articular capsule (joint capsule) and the joint cavity of synovial joints
