Study Notes
Joint Classification
- Diarthrosis: Freely movable joint
- Syndesmosis: Fibrous joint where collagen fibers hold two parallel bones together
- Suture: Fibrous joint; found only in the skull; short collagen fibers
- Synovial: Freely movable joint; surrounded by a joint capsule lined with synovial membrane; contains synovial fluid
- Synostosis: Fused bony joint
Synovial Fluid Function
- Synovial fluid does not perform the following function:
- Not a function: Forming cartilage
- Nourishing cartilage
- Lubrication
Cartilaginous Joints
- Synchondrosis: Temporary cartilaginous joint; usually replaced by bone tissue; example: epiphyseal plate
- Cartilaginous joint: Articulation that connects two bones primarily using cartilage; classified as Synchondrosis
Additional Joint Types
- Syndesmosis: Example: tibiofibular ligament. Amphiarthrotic (limited movement)
- Gomphosis: Special fibrous joint; tooth in socket (e.g., periodontal ligaments)
- Mensici: Cushioning structures in some synovial joints.
- Intracapsular and extracapsular ligaments: ligaments that reinforce the joint capsule
- Collateral ligaments: Ligament that lies along the sides of a joint, often reinforcing other joint ligaments.
- Intervertebral Disc: Contains nucleus pulposus.
Joint Types: Further Clarification
- Synchondrosis: Immovable cartilaginous joint.
- Gomphosis, (a fibrous joint): Not a fibrous, cartilaginous, or synovial joint.
