  1. The Skeleton Function & Bones

  2. Skeleton • How many bones in the body?? • Does anyone know any bones in the body??

  3. Why do we have bones?? • Support – if we had no bones we would be a pile of jelly!

  4. Why do we have bones?? • Movement – Allow use to walk, run etc. • Protection – Protects our inner organs.

  5. The Skeleton Types of Joints

  6. Skeletal Joints Song • https://www.youtube.com/watch?v=WHNO6D1Ee0Q

  7. What are joints? • Joints are where bones meet & they allow for movement. • Some examples are the skull, hip, shoulder, knee, elbow.

  8. Hinge Joints • Allows movement in one direction only. • Examples include the elbow & knee

  9. Ball & Socket Joints • Allow movement in many directions. • Examples include the hip [between hip (socket) & top of femur (ball)] & the shoulder.

  10. Fused Joint • No movement between the bones that meet. • An example is the skull. • The skull protects your brain

  11. Ligaments • Join bone to bone

  12. Questions. • Name the 3 types of joints & their function. • Give an example of each. • What does the term ligament mean?

  13. The Skeleton Structure of Synovial Joint

  14. Ligament! • What is a ligament from the last class?? • Ligament joins bone to bone.

  15. Synovial Joint • A movable joint. • Examples include elbow, knee, hip.

  16. Synovial Joint Structure

  17. Cartilage = A shock absorbing cushion that prevents friction between the bones. • Synovial Fluid = Lubricates the joint to allow for easy movement. • *Cartilage can be found in the spine & prevents vertebraerubbing off each other.*

  18. Synovial Joint Structure

  19. Draw a labelled diagram of the Synovial Joint in your copy.

  20. The Skeleton Antagonistic Muscles

  22. Tendon • Connects muscle to bone.

  23. What does Antagonistic mean?? • Antagonistic = Opposing/competing. • Antagonistic muscles work opposite one another. • They work in pairs

  24. An Antagonistic Pair

  25. Experiment. • Hold your arm out straight. • Which muscle contracted & which on relaxed?? • The Bicep relaxed & the tricep contracted.

  26. Experiment. • Now hold your arm out straight & bend your elbow. • Which muscle contracted & which relaxed? • The Bicep contracted & the Tricep relaxed.

  27. Define antagonistic muscle. • What happens when you hold your arm out straight? • What happens when you then bend your elbow? • What is a tendon?
