  3. Main Parts of Human Skeleton head ribcage backbone arm pelvis leg

  4. Location of main bones

  5. Location of main bones skull collarbone shoulder blade rib humerus vertebra ulna pelvis radius femur tibia fibula

  6. Functions of skeleton • Support • Movement • Protection

  7. Can you remember? What are those three functions? Support Protection Movement Hold us upright Ribs protect the lungs heart etc Anchor for the muscles

  8. Getting about…. Movement

  9. biceps radius humerus ulna Bones and muscles of the arm

  10. biceps radius humerus ulna How would YOU raise the arm?

  11. triceps relaxes Muscles work in pairs (antagonistic pairs) bone pulled upward

  12. biceps humerus radius ulna triceps How would you lower the arm?

  13. They are called an antagonistic pairs biceps relaxes bone pulled downward

  14. Watch the muscles….

  15. They only contract

  16. They can not push

  19. That’s why they work in pairs

  20. They are called an antagonistic pairs

  21. A Synovial Joint Ligaments hold the bone together Membrane Synovial fluid stops wear Cartilage protects end of bone Capsule Bone

  22. Connective Tissue Ligament bone connected to bone Cartilage protects end of bone Tendon Muscle to bone

  23. A Joint is where the bones are allowed to move about each other, this is called a hinge

  24. Bone Marrow • Red blood cells are made in the marrow or inside of the bones

  25. Can you remember? How many functions does the skeleton have? 3

  26. Can you remember? What are those three functions? Support , Protection and Movement Tendon, Cartilage and ligament Joints types – Ball and socket, hinge, pivot and fused

  27. H/w • P67 • Q 1,4,5,6.
