Different Types of Joints in the Human Body

There are three main types of joints in the human body.  The three types of joints are called: hinge joint, ball and socket joint, and gliding joint.  Each of these joints is located in a different part of the body, and each joint has a different function.

Ball and socket joint:
The ball and socket joint is a joint that is capable of moving a bone 360 degrees.  In this joint, one round bone fits into another cup-like bone.  This joint can be found in the hip and the shoulder.

Hinge joint:
The hinge joint is a joint that only allows motion backward and forward.  It can be compared to a hinge on a door.  The knee and the elbow are examples of this type of joint.

Gliding joint:
The gliding joint only allows gliding or sliding movement.  This joint is made up of bones that move over each other in quick patterns.  These joints are found in the wrist and ankles.
