Across
  1. 3. the hand bones
  2. 8. a flat bone that protects the heart
  3. 11. the section of the spine that connect to the ribs
  4. 12. the lower back
  5. 14. a type of synovial joint that allows a wide range of movement (sideways,backwards/forwards, rotation), e.g. hip
  6. 16. a long bone often called the shin bone
  7. 19. 12 pairs of flat bones that protect the lungs
  8. 20. a type of bone tissue that provides some of the shock absorption required at the end of long bones or at the edges of more irregular bones
  9. 23. a long bone, the largest bone of the body
  10. 25. a feature of synovial joints. Lubricates the inside of the joint
  11. 27. a function of the skeletal system where the skeleton provides ________ to internal organs such as the heart, lungs and the brain.
  12. 32. a long bone, the thumb side forearm bone
  13. 33. a sesamoid bone often called the knee cap
  14. 34. these are inelastic and very strong, allowing movement by helping muscles pull through the joint and on the bones
  15. 36. production of this occurs within the marrow of long bones
  16. 39. the finger and toe bones
  17. 42. also known as growth plates, are the centres for bone growth
  18. 43. one of the three bones that make up the shoulder girdle, commonly called the shoulder blade
  19. 44. bones that have a key role of protection. eg. the bones of the skull
  20. 45. a function of the skeletal system where bones store calcium, phosphorous and small amounts of magnesium, sodium and chlorine.
Down
  1. 1. the pinky side forearm bone
  2. 2. the neck bones
  3. 4. allows movement in only one direction (backwards/forwards), e.g. elbow
  4. 5. a feature of synovial joints. Lines the inside of the capsule / produces & secretes synovial fluid
  5. 6. found in the shaft or diaphysis of the long bone. This comparatively solid bone surrounds the cavity of the long bone, offering an extremely strong
  6. 7. joints that offer no movement. Ex. the skull
  7. 9. Allows movement in two directions (sideways, backwards/forwards), e.g. thumb
  8. 10. have no regular shape characteristics
  9. 13. type of joint that offer a full range of movement and move freely in at least one direction. Ex knee
  10. 15. they cross over joints, joining bone to bone. Their slight elasticity allows small movement from the bones of the joint.
  11. 17. slightly moveable, joints are joined by cartilage and allow small movements. Ex. vertebrae
  12. 18. long bones of the foot
  13. 21. a feature of synovial joints. Lines the bones / protects / reduces friction
  14. 22. a smooth, slightly elastic tissue found in various forms within the body such as hyaline, vertebral discs, ribs joints, nose and ears
  15. 24. also called the spine, provides the central structure for the maintenance of good posture
  16. 25. small bones developed in tendons around some joints; for example, the patella
  17. 26. type of bone, longer than they are wide, and they have a hollow shaft containing marrow
  18. 28. a feature of synovial joints. Surrounds the joint / adds stability / stops substances entering or leaving joint
  19. 29. the wrist bones
  20. 30. Allows only gliding or sliding movements (sideways, backwards/forwards), e.g. carpals of the wrist
  21. 31. commonly called the jaw bone
  22. 35. sometimes called the tail bones
  23. 37. one of the three bones that make up the shoulder girdle, commonly called the collar bone
  24. 38. are roughly cubical, with the same width and length; for example, the carpals of the wrist
  25. 40. a long bone and one of the three bones that make up the shoulder girdle, commonly called the upper arm bone
  26. 41. short bones of the ankles
