Across
  1. 1. Bone which is strong and protects and attaches muscle e.g. cranium
  2. 9. Found in the thigh, this is the longest bone.
  3. 10. Bone which has an unusual shape e.g. mandible
  4. 13. The most common joint, and is separated by ligaments and syvonial fluid e.g. the knee.
  5. 14. Bones contain large amounts of this
  6. 16. The connective tissue which contains collagen and elastin.
  7. 17. They rock back and forth and side to side e.g. thumbs.
  8. 18. Bone which is the same length as width, and has lots of bone marrow e.g. carpals
  9. 19. This occurs when a bone pops out of the joint
  10. 20. A rounded head fits into a cup e.g. hip
  11. 23. Supports the limbs and gives them attachment
  12. 24. Something part of the skeletal system that is not counted as a bone
  13. 26. Movement around an axis e.g. neck
  14. 27. Clavicle, Scapula, Humerus are all found where?
  15. 29. There are 206 of these in the adult skeleton
Down
  1. 2. Bone which is longer and thinner, hard on the outside with a spongy center.
  2. 3. They link bone to muscle and allow movement.
  3. 4. Acromion Scapular is an injury which happens when overworked.
  4. 5. The knee bone.
  5. 6. The number of pairs of ribs an adult skeleton has.
  6. 7. A protein that gives the skeletal system elasticity.
  7. 8. They link bones together and prevent dislocation
  8. 9. This happens when a bone cracks and bleeds.
  9. 11. Two flat bones are held together by ligaments and glide against each other e.g. ankles
  10. 12. A joint which separates bone by a thin layer of tissue e.g. skull
  11. 15. Supports the main axis of the body e.g. neck
  12. 16. Is moveable and connected by cartilage e.g. ribs or sternum
  13. 21. The percentage of body weight the skeletal system makes up
  14. 22. Bone Marrow which produces red blood cells and is found in spongy bone.
  15. 25. Bone Marrow which is found in the centre of the marrow cavity and makes up white blood cells.
  16. 28. Convex surface and concave fit and move in one direction e.g. elbow
  17. 30. The 3 bones, malleus, incus, stapes are the smallest in the body. Where are they found?
