what is the difference between hinge joint, ball and socket joint, pivot joint and gliding joint?
Answers
ball-and-socket joint: Joint where the ball-shaped surface of one bone fits into the cup-like shape of another; examples include the hip and shoulder.
A gliding joint is a joint which allows only gliding movement. The gliding joint allows one bone to slide over the other. The gliding joint in your wrist allows you to flex your wrist. It also allows you to make very small side-to-side motions. There are also gliding joints in your ankles
The pivot joint only allows rotating movement. An example of a pivot joint is the joint between the radius and ulna that allows you to turn the palm of your hand up and down.
In a hinge joint, the ends of the bones are shaped in a way that allows motion in two directions, forward and backward. Examples of hinge joints are the knees and elbows.
