Diffrent types of joints of the body
Slightly movable joints are sometimes called cartilaginous joints.
The bones are separated by a cushion of cartilage. The joints between the vertebrae in the spine are cartilaginous joints.
The bones can move a little bit, but ligaments stop them moving too far. This is why we can bend, straighten and rotate through the back, but not too far.
90% of the joints in the body are synovial joints. They are freely movable.
Synovial joints contain synovial fluid which is retained inside a pocket called the synovial membrane. This lubricates or ‘oils’ the joint.
All the moving parts are held together by ligaments.
These are highly mobile joints, like the shoulder and knee.
