3 types of joints

Fibrous, Synovial, Cartilaginous
Types of synovial joints
- Uniaxial
- 1. Hinge (i.e. Knee)
- 2. Gliding (i.e. intercarpal
- 3. Pivot (i.e. Superior radioulnar jt)
- Biaxial
- 1. Saddle (capometacarpal thumb)
- 2. Condyloid (metacarpalphalangeal)
- 3. Ball & Socket (glenohumeral)
Types of Fibrous joints
- 1. Suture: In cranium
- 2. Gomphoses: teeth
- 3. Syndesmosis: Interosseous membrane
Types of Cartilaginous joints
- 1. Synchondrosis: hyaline joint to bone... called synostosis when hyaline ossifies
- 2. Symphesis: fibocartilaginous disc (pubic symphesis)
