Pivot joint
You can move side to side and sometimes up and down but never the full way round
Ball and socket joint
This can move around about 360° and are layered with cartilage. They also have a fluid called synovial fluid between them
Fixed joint
These are joints that are just connected bone straight to bone and have nothing in between them
Hinge joint
It can turn 180° but only one way(up or down) it will never be able to go both ways with this joint unless the bone is broken
How many bones does our body have?
We have more than 200 bones in our body
What is the longest bone in the body?
The femur in your leg is the longest bone in the body
