1. Joints in the Human Body

2. 3 Categories of Joints Fibrous Synovial Cartilaginous
Synarthrosis = no movement
Skull sutures, teeth
Synovial
Diarthrosis = full movement
Knee, elbow, hip
Cartilaginous
Amphiarthrosis = some movement
Spine

3. 6 Types of Synovial Joints
Gliding
Hinge
Pivot
Condyloid
Saddle
Ball and socket

4. Gliding Joints move against each other on a single plane
Bones of wrist and ankles
Intervertebral joints

5. Hinge Joints move on just one axis. Allow for flexion and extension
Elbow and finger joints

6. Pivot Provides rotation
At top of spine the atlas and axis form a pivot joint that allows the head to rotate

7. Condyloid Allows for circular motion, flexion, and extension
Wrist joint between radius and carpal bones

8. Saddle
Allows for flexion, extension, and other movements – but no rotation
Opposable thumb

9. Ball and socket Freely moving joint that can rotate on any axis
Hip and shoulder
