Topic Progress:

Joints can be classified according to function and structure.

The functional classification is based on how much movement is allowed at the joint.

According to function we differentiate between joints which are

  • synarthrotic
  • amphiarthrotic
  • diarthrotic

When we have a look at the structure we refer to the methods and materials that tie the bones together and separate them into:

  • fibrous
  • cartilagenous
  • synovial joints

Although this does not always hold true, for most of the joints we can say that:

  • Fibrous joints are synarthrotic
  • Cartilagenous joints are amphiarthrotic
  • Synovial joints are diarthrotic


In the next couple of lessons we will have a more detailed look at the structural and functional classification of joints and discuss their major differences.
