  1. ARTICULATIONS

  2. Functional classification • Synarthrosis (es) • Amphiarthrosis • Diarthrosis

  3. Structural classification • FIBROUS • SUTURE (synarthrosis) • SYNDESMOSIS (amphiarthrosis) • GOMPHOSIS (synarthrosis)

  4. Structural Classification • Cartilaginous • Synchondrosis (epiphyseal plate, synarthrosis) • Symphysis (amphiarthrosis)

  5. Structural Classification • SYNOVIAL

  6. SYNOVIAL • Joint cavity/Synovial cavity • Articular Cartilage • Articular Capsule • Synovial Membrane • Synovial fluid • Outer fibrous layer

  7. SYNOVIAL • Ligaments • Accessory ligaments e.g. cruciate • Menisci • Bursae

  8. ANGULAR MOVEMENTS • Flexion, Dorsiflexion • Extension, Hyperextension, Plantar flexion • Abduction, Adduction • Rotation • Circumduction • Inversion, Eversion
