Ball and Socket Joint Hinge Joint Pivot Joint Gliding Joint

Hinge Joint

Works like the hinges in a door. This kind of joint only allows back and forth

movement. Bones in the knee, elbow, fingers and toes have this type of joint.
Ball and Socket Joint

In this type of joint, one end of the bone is round like a ball. This round end fits
into another bone which is like a socket. The round bone can rotate in the

socket. It allows movement in almost all directions. This joint is found in our
hips and shoulders.

Pivot Joint

The pivot joint is between the first and the second vertebrae of the backbone.
The skull is connected to the first two vertebrae of the vertebral column with a

pivot joint. It allows the rotating movement from side to side.
Gliding Joint

This type of joint is found between the small bones of the wrist and ankles.

It allows sliding movements. The movement allowed is a simple gliding back
and forth or sideways.

MUSCLES

Bones in the body cannot move

on their own. They move with
the help of muscles. We have
more than 600 muscles in our

body. Most of them are attached
to the bones with strong fibers

called tendons . The tendons
help the muscles in moving the

bones.
