  1. 2. This part of the skeletal system is made up of the arms, legs, pelvis, and shoulders.
  2. 4. This is part B on the bone structure diagram.
  3. 5. Inside compact bone, blood vessels enter the bone through these structures that run parallel to the long axis of the bone.
  4. 6. Inside compact bone, blood vessels enter the bone through these structures that run perpendicular to the long axis of the bone.
  5. 7. Connective tissue in the spaces of spongy bone. This type of bone marrow is where blood cells are produced.
  6. 9. This is part C on the bone structure diagram.
  7. 12. This is part E on the bone structure diagram.
  8. 14. This is part A on the bone structure diagram.
  9. 16. This type of bone marrow is where fat is stored within the medullary cavity or in the spaces of spongy bone.
  10. 18. When bones grow or change their shape, these cells break down bone minerals.
  11. 20. This is part of a long bone that develops from a center of ossification from the diaphysis.
  12. 21. The inner layer of a joint capsule has cells that produces this fluid to help the joint move smoothly.
  13. 23. This is part D on the bone structure diagram.
  14. 24. The place where one or more bones meet another bone.

  1. 1. When bones stop growing in length, this structure is formed that separates the epiphysis from the diaphysis.
  2. 3. Bones are made up of inorganic material, such as calcium, and organic material, such as this.
  3. 8. In a long bone, this structure, or shaft, is composed mostly of compact bone but can also have spongy bone.
  4. 10. Bones connected by cartilage.
  5. 11. The structure of joints contains a capsule that helps hold bones together while still allowing for movement.
  6. 13. Connective tissue made up of protein fibers, such as collagen and elastin.
  7. 15. In bone development, these structures secrete mineral deposit that replace cartilage.
  8. 17. This part of the skeletal system consists of the skill, vertebral column, and rib cage.
  9. 19. These cells help to maintain the minerals in bone tissue and continue to strengthen it.
  10. 22. Connective tissue that holds bone together in a joint.
