What are the joint surfaces?

joint surfaces are parts of bones that come into contact inside the joint. These bony surfaces can be flushed to each other, as in the joints of sewing between the bones of the skull, or they can be separated by a cartilage disc, as in the knee joint. Whatever the joint type, either ligaments or cartilage are connected to neighboring bones. In addition, the joints are classified according to their structure - ie the shape of their joint surfaces. For example, as those found at the base of the thumb, they are thus named for the way the end curves of the adjacent bones are like two saddles, so they are also called saddle joints. In the fibrous joint, the joint surfaces are almost completely flushed, separated only by the matrix of the connective fibers based on collagen. An example may be a view in the skull of the skull, where the bones surrounding the brain fit together like curved plates. Like boards found in the Earth's crust, howeverAvidal and during the first few years of life gradually combine.

In cartilage joints, the joint surfaces are connected by a flexible cartilage that allows a small amount of movement between neighboring bones. This cartilage covers the ends of the bones and also fills the space between the bones. The bony surfaces are usually rough, as in the manubrioteric joint in the bone of the breast, where the manubrium or the upper part of the chest meets the body of the chest.

Synovial joints are the most numerous in the body. These are movable joints such as shoulders and knee joint. They are classified according to their structure and function, as shapes are determined by joint surfaces. For example, in a flat or sliding joint, the joint surface of each bone is relatively flat and smooth so that the bones can slide together.

joint with a ball and ostuch such as a shoulder joint, on the other side has a rounded head of one bone that is in a similarrounded outlet of the other. As such, the joint surfaces are much larger in the joint with the ball with the ball and the osnaver. They cover a more substantial surface area than those observed in other types of joints.
