2. Joint Types Fibrous Joints: Bound together by connective tissue.
Allow no movement.
Example:
Sagittal suture

3. Joint Types 2. Cartilaginous Joints Provides bone to bone attachment.
Allows some movement.
Example: Costal Cartilage (Ribs).

4. Types of Joints 3. Synovial Joints
The bony surfaces are separated by lubricating fluid and cartilage.
Allow for the most movement.
Example: Shoulder, Knee Joints.

5. Synovial Joints Contain: Articulating cartilage: At ends of bones.
Joint cavity: Filled with synovial fluid which acts as a lubricant.
Joint capsule: Surrounds jt. cavity.
Bursa: fluid filled sacs that decrease friction between structures.

6. Types of Synovial Joints
Ball and Socket: Allows all movements. E.g., shoulder
Pivot: Allows for rotation. E.g., radioulnar, vertebrae.
Saddle: Allows all motions except rotation. E.g., thumb.

7. Types of Synovial Joints
4. Ellipsoid: A reduced ball and socket – limited rotation. E.g., wrist.
5. Hinge: Allows flexion / extension. E.g., knee.
6. Gliding: Connects relatively flat bones. E.g., carpals, tarsals.
