Across
- 2. This part of the skeletal system is made up of the arms, legs, pelvis, and shoulders.
- 4. This is part B on the bone structure diagram.
- 5. Inside compact bone, blood vessels enter the bone through these structures that run parallel to the long axis of the bone.
- 6. Inside compact bone, blood vessels enter the bone through these structures that run perpendicular to the long axis of the bone.
- 7. Connective tissue in the spaces of spongy bone. This type of bone marrow is where blood cells are produced.
- 9. This is part C on the bone structure diagram.
- 12. This is part E on the bone structure diagram.
- 14. This is part A on the bone structure diagram.
- 16. This type of bone marrow is where fat is stored within the medullary cavity or in the spaces of spongy bone.
- 18. When bones grow or change their shape, these cells break down bone minerals.
- 20. This is part of a long bone that develops from a center of ossification from the diaphysis.
- 21. The inner layer of a joint capsule has cells that produces this fluid to help the joint move smoothly.
- 23. This is part D on the bone structure diagram.
- 24. The place where one or more bones meet another bone.
Down
- 1. When bones stop growing in length, this structure is formed that separates the epiphysis from the diaphysis.
- 3. Bones are made up of inorganic material, such as calcium, and organic material, such as this.
- 8. In a long bone, this structure, or shaft, is composed mostly of compact bone but can also have spongy bone.
- 10. Bones connected by cartilage.
- 11. The structure of joints contains a capsule that helps hold bones together while still allowing for movement.
- 13. Connective tissue made up of protein fibers, such as collagen and elastin.
- 15. In bone development, these structures secrete mineral deposit that replace cartilage.
- 17. This part of the skeletal system consists of the skill, vertebral column, and rib cage.
- 19. These cells help to maintain the minerals in bone tissue and continue to strengthen it.
- 22. Connective tissue that holds bone together in a joint.
