Across
- 2. Small, beam-like structures within spongy bone that provide support and resistance to compression.
- 10. Cells responsible for producing new bone tissue.
- 12. The shaft or long, central part of a long bone.
- 13. A natural opening or hole in a bone that allows for the passage of nerves and blood vessels.
- 14. The process by which cartilage is transformed into bone.
- 15. The function of joints and muscles working together to enable body motion.
- 16. The dense outer layer of bone that provides strength and structure.
- 21. The production of blood cells in bone marrow, known as hematopoiesis.
- 23. A hormone that regulates calcium levels by breaking down bone when calcium is low.
- 24. The highly movable joints surrounded by a fluid-filled capsule.
- 25. The part of the skeleton that includes the limbs and girdles (shoulders and hips).
- 26. A collection of blood outside of blood vessels, often occurring after bone injury.
- 27. Bone cells that break down and reabsorb bone tissue.
- 30. The joints connected by fibrous tissue, allowing little to no movement.
- 33. A hormone produced by the thyroid gland that helps regulate calcium levels in the blood.
- 35. Points where two or more bones meet, allowing movement.
- 37. Smooth tissue at the ends of bones that allows for frictionless joint movement.
- 38. The process of forming red and white blood cells in bone marrow.
Down
- 1. The hollow area or cavity in the diaphysis of a long bone, containing bone marrow.
- 3. The growth plate, a layer of cartilage that allows bones to grow in length.
- 4. The part of the skull that encloses the brain.
- 5. The discs or pads of cartilage between vertebrae that cushion and allow movement.
- 6. The strong connective tissue that attaches muscles to bones.
- 7. Crystalline mineral that gives bones their hardness and strength.
- 8. The ends of a long bone, often involved in joint movement.
- 9. The function of bones in storing minerals and fat for the body.
- 10. Mature bone cells responsible for maintaining bone tissue.
- 11. The function of bones to bear the weight of the body.
- 14. The organic part of bone matrix, primarily composed of collagen.
- 17. A dense layer of tissue covering the outer surface of bones.
- 18. The joints where bones are connected by cartilage, allowing limited movement.
- 19. Layers of bone tissue found in osteons.
- 20. Tiny channels that connect osteocytes, allowing nutrient and waste exchange.
- 22. The central part of the skeleton, including the skull, spine, and ribcage.
- 28. The porous, inner part of bone that reduces its weight and contains bone marrow.
- 29. The system or framework of bones and cartilage that supports and protects the body.
- 31. Structural units of compact bone, arranged in concentric circles.
- 32. The role of bones in encasing and safeguarding vital organs.
- 34. The tough connective tissue that connects bones to other bones at joints.
- 36. The individual bones that make up the spinal column.
