    place of contact between bones, bone and cartilage, or bones and teeth.
  2. Structural Classification: Fibrous Joint
    • has no joint cavity
    • bones held together by dense connective tissue
  3. Structural Classification: Cartilaginous Joint
    • has no joint cavity
    • joined by cartilage
  4. Structural Classification: Synovial joint
    • fluid- filled joint cavity seperating surfaces of bones
    • surface enclosed within connective tissue
    • bones attached by ligaments
  5. Functional classification: Synarthrosis
    immobile joint (fibrous or cartilaginous)
  6. Functional classification: Amphiarthrosis
    • slightly mobile joint
    • (fibrous or cartilaginous)
  7. Functional classification: Diarthrosis
