1. Classication by structure:
    Fibrous, cartilaginous, synovial
  2. Classification by function
    • Synarthrosis
    • -Synarthrodial

    • Amphiarthrosis
    • -Amphiarthrodial

    • Diarthrosis
    • -Diarthrodial
  3. Synarthrodial
    • Suture:
    • -Cranial bones
    • - Immovable beyond infancy.


    • -Sockets of teeth
    • -Conical Peg fits into socket
    • -Minimal or no movement
  4. Amphiarthrodial
    • Slightly moveable joints.
    • -Syndesmosis- helf together by strong ligamentous structure that allow minimal movements between the bones.

    - Inferior tibiofibular joint.
  5. Amphiarthrodial

    -Separated by fibrocartilage pad that allows slight movement.

    -Symphysis pubis, intervertebral joints.

    • Synchondrosis
    • -Seperated by hyaline cartilage
    • -allows slight movement
    • -Costochondral joints.
  6. Diarthrodial
    Synovial/freely movable.

    joint capsule surrounds ends of bone forming joint.

    Synovial capsule lines joint capsule

    Area inside joint capsule= joint cavity

    Thickened portions of capsule= ligament.
  7. Diarthrodial
    Ligaments may be contained:

    -Within the capsule iteself.

    -Intraarticularaly ---> ACL

    • -Extraarticularaly ---> LCL
    • fibular collateral ligament.
  8. Diarthrodial
    • Hyaline Cartilage
    • -helps protect ends of long bones. (Compressible and elastic)

    -Relies on movement for feeding. (Works like a sponge)

    Articular surface has low friction due to synovial fluit.
  9. Diarthrodial
    Some joint in this category have a fibrocarilage disk located between articular surfaces. (extra shock absorption.

    • -Meniscus
    • -Glenoid/acetabular labrum.
  10. Arthrodial
    • Gliding/plane joint.
    • Two flat bony surfaces that butt against one antoher.
    • limitied gliding movement
    • Carpal joints
  11. Condyloidal
    • Biaxial ball and socket.
    • Allows movement in two planes without rotation.
    • Radiocarpal joint.
  12. Enarthrodial
    • Multiaxial ball and socket
    • movement in all planes
    • Shoulder and hip.
  13. Ginglymus
    • hinge
    • wide range of movement in only one plane.
    • Elbow, ankle, knee
  14. Sellar
    • Suddle
    • Thumbs only-Carpometacarpal joint
    • Permits ball and socket movement. - with exception of slight rotation.
  15. Trochoidal
    • Pivot or screw joint
    • Rotation movement around long axis.
    • Radioulnar joint. -Rotation of radius
