How Are Joints Held Together?

A joint is basically the point at which two or more than two bones come in contact with each other. They are so developed to facilitate the movement and for the provision of mechanical support, and can be categorised in structural terms as well as functional terms.

Classification based on the structure is established by figuring out in what way the bones link to each other, whereas classification based on function is established on the degree of motion which is present between the articulating bones. However in reality there is quite a lot of overlapping between the two types of classifications as mentioned previously.  Hence, it is actually the joints which hold the bones together, rather then the joints being held together by anything.

For instance, the extremely mobile diarthoses joints are synovial ones, although the former term describes its functional classification while the latter describes its structural classification.
