Joints

Ball and Socket
The ball and socket joint allows your arms and hips to move in many directions.  Up Down, right, left, and a full 360.  This rotation gives you a lot of freedom to get where you want to go!
 

Hinge
The bones in the knees, elbows, fingers, and toes move just like the hinges on a door.  The movement is somewhat limited, and it can only swing back and forth. The Same thing goes for your knees, elbows, fingers, and toes.

Hinge
The first two vertebrae in your neck and the joint beneath your elbow move in a semicircle motion by twisting against each other.

Pivot
The bones in the wrists and ankles slide against each other in a gliding motion. The gliding joint gives your wrists and ankles lots of freedom so you can really move around.
