## Connecting bones

The bones in our body are connected in different ways. Without these connections we would nog be able to move or our skeleton would not be able to support is. There are five ways in which the bones are connected: Joints, sutures, fontanelles, cartilaginous joints and intervertebral discs.

Joints are places were bones meet. In some of these places, a lot of movement is possible, such as in your knee or elbow but other joints can not move at all. The bones in your skull for instance are fused together at the joints forming a hard protective cover for your brains. These joints are called suture. During the first two years of a person's life, these bones fuse togther but while there's still space between them, a thick membrane called the fontanelle protects the openings.

Some joints allow for just a little bit of movement. These are cartilaginous joints. two bones are connected by cartilage such as the ribs and the sternum or between the hipbones. Finally the joints between the vertebrae are intervertebral discs. These discs from cartilage connect the vertebrae together while the spinal nerve (ruggenzenuw) goes through them.
