  9. 4 classifications of joints
    • Functional
    • Structural
    • Fibrous

  10. Functional joints
    Classification of joints based on ability to move or lack thereof.
  11. Structural joints
    • Primary classification system of joints.
    • Based on three types of tissue that separate ends of joint bones.
    •   Fibrous

    Secondary center
    Epiphysis ( growth plates )
  15. Functional joint
      Synarthrosis...
    imovable joint
