| Front | Back | 
| 
								Plane Joints									 | 
								Flat Surfaces--only gliding movements allowed (example: triquetrum and hamate)									 | 
| 
								Hinge Joints									 | 
								Cylinder in a tough--flexion or extension on a single plane (example: humerus, radius, and ulna at elbow)									 | 
| 
								Pivot Joints									 | 
								Ball or point in a "sleeve" --allow rotation or circumduction (example: neck)									 | 
| 
								Condyloid Joints									 | 
								Two oval articular surfaces--permit all angular movements (example: metacarpal and phalanx)									 | 
| 
								Saddle Joints									 | 
								Each artricular surface is convex and concave--allow more movement than condyloid joints (example: trapezium and first metacarpal in thumb)									 | 
| 
								Ball-and-socket joints									 | 
								Rounded head fits into a cup--most freely moveable joint type (example: shoulder, hip)									 |
