  • 1. Classification of Articulations
    By Sadie Gordon & Bob
  • 2.
  • 3. Classification of joints
    Functionally
    Fibrous
    Dense Regular Connective Tissue
    Cartilaginous
    Cartilage
    Synovial
    Fluid Filled Joint Cavity
    Structurally
    Synarthrosis
    Immobile
    Amphiarthrosis
    Slightly Movable Joint
    Diarthrosis
    Freely Mobile Joint
  • 4. Functional Classification
    Synarthrosis
    An Immobile Joint
    Amphiarthrosis
    Slightly Mobile Joint
    Diarthrosis
    Freely Mobile Joint
  • 5. Structural Classification
    Fibrous
    Dense irregular connective tissue that holds bone to bones
    No joint cavity
    Cartilaginous
    Pad of cartilage wedged between bones
    No Joint cavity
    Synovial
    Ends of bones are covered with cartilage
    Joint capsule is lined with synovial fluid
    All synovial joints are freely moveable (diarthrotic)
  • 6.
  • 7. Fibrous Joints
    Gomphosis
    Suture
    Syndesmosis
  • 8. Gomphosis
    • Membranes that holds tooth in the Jaw
    • 9. Example tooth in the Jaw
    Functionally classified as Synarthrosis (immobile)
  • 10. Suture
    • Dense regular connective tissue that connects skull bones
    • 11. Example: Lambdoid Suture
    • 12. Functionally Classified as Synarthrosis
  • Syndesmosis
    • Dense regular connective tissue fibers between bones
    Examples: Syndesmosesare the articulations between the fibula and the fibula, and the radius and the ulna
    Functionally classified
    as Amphiarthroses(slightly moveable)
  • 13. Types of Cartilaginous Joints
    Synchondrosis
    Symphysis
  • 14. Synchondrosis
    • Hyaline cartilage plate between bones
    • 15. Examples: Epiphyseal plates, and Costochondral joints
    • 16. Functional Classified as Synarthrosis
  • Examples of Synchondrosis Joints
  • 17. Symphysis
    • Fibrocartilage pad between bones
    • 18. Examples: Pubic symphysis, and intervertebral disc
    • 19. Functional classified
    as Amphiarthrosis
  • 20. Synovial
    Uniaxial
    Plane joint
    Hinge Joint
    Pivot joint
    Biaxial
    Condylar joint
    Saddle joint
    Multiaxial
    Ball-and-socket joint
  • 21.
  • 22. Uniaxial
    • Plane joint
    Flattened or slightly curved faces slide across on another
    Example: Intercarpal joints & Intertarsal joints
    Functionally Classified as Diarthrosis
    • Hinge Joint
    Permits angular movements in a single plane
    Example: Elbow Joint
    Functionally Classified as Diarthrosis
    • Pivot joint
    Permits rotation only
    Example: Atlantoaxial joint
    Functionally Classified as Diarthrosis
  • 23. Biaxial
    • Condylar joint
    Oval articular surface on one bone closely interfaces with a depressed oval surface on another bone
    Examples: MP joints
    Functionally Classified as Diarthrosis
    • Saddle joint
    Saddle-shaped articular surface on one bone closely interfaces with depressed surface on another bone
    Example: Articulation between carpal and first metacarpal bone
    Functionally Classified as Diarthrosis
  • 24. Multiaxial
    • Ball-and-socket joint
    Round head of one bone rests within cup-shaped depression in another bone
    Example: Glenohumeral joint, and hip joint
    Functionally Classified as Diarthrosis
