Learning time​

Kids learn by watching short, engaging video lessons.

When two bones meet, what do we call them? It's a joint. Our joints help us to move. There are three classifications of joints. First, we have immovable joints. These are joints that don't move. These are things like the joints or where your bones meet in your skull. Then we have partially movable joints. These are joints that sometimes move a bit like the vertebrae in our spine that are connected by cartilage. And finally, we have movable joints. These are joints that help our bones to move and twist and turn, things like our elbow, our ankle, our shoulder. Our freely movable joints can then be classified into three different sets. We have hinge joints. These are joints that open and close like our elbow. We also have ball and socket joints, joints like our shoulder or our hips where we can move in all directions. And finally, we have pivot joints that allow us to turn and twist like the joints that connect our head to our spine.
