There are joints all throughout your body. A joint is created when 2 or more bones meet. There are 3 main types of joints:
Fibrous, Catilaginous and Synovial
Joints
Fibrous joints are also called fixed joints, because they do not move.
The bones are held together by fibrous connective tissue and have no joint cavity.
Your skull is actually made of many pieces, which are connected and eventually fused together.
Fibrous joints also hold your teeth in place.
Cartilaginous joints
These joints are connected entirely by catrilage. Although they allow more movement that fibrous joints, they are not as flexible as Synovial joints.
Your spinal cord is an example of a cartilaginous joint.
However if we look at a babies skull, the pieces have not fussed together. This is too allow for an easier birth.
Babies actually have a soft spot on the top of their heads. Infants skull hasn’t totally fused over, meaning if you place your thumb on the top of their head you can feel their pulse on their brain.
This soft spot is only about a 20 cent piece big.
Synovial joints
These joints are the most common in the body. They have the greatest range of movement and have a synovial capsule surrounding the entire joint, a synovial membrane and cartilage.
