A JOINT IS WHERE TWO BONES COME TOGETHER.

TWO TYPES OF JOINTS ARE THE BALL-AND-SOCKETS AND THE HINGE.

THE MOVEMENT OF THE HINGE LETS YOU DO IT TO BEND AND STRAIGHTEN IT.

THE LOOKS OF THE HINGE IS ELBOW LIKE.

THE MOVEMENT IT ALLOWS YOU TO DO IS MOVE YOUR BODY IN DIFFERENT DIRECTIONS

THE BALL-AND-SOCKET LOOKS LIKE A HIP AND SHOULDER BLADE.

THERE IS BONE, MUSCLE AND TENDON TISSUE.

THIS HELPS YOU BY MOVING SOOTHLY, NOT RUBBING ON THE BONES

IS WHEN THE JOINTS ARE SWELLING AND WEARING OUT.
