Document Summary
Joints are the weakest parts of the skeleton. Joints are classified by structure and by function. The functional classification is based on the amount of movement. Our joints have two fundamental functions: they give our skeleton mobility, and they hold it together, sometimes playing a protective role in the process. 8. 1 joints are classified into three structural and three functional categories classification focuses on the material binding the bones together and whether or not a joint cavity is present. Structurally, there are fibrous, cartilaginous, and synovial joints. Only synovial joints have a joint cavity. allowed at the joint. On this basis, there are synarthroses, which are immovable joints; amphiarthroses, slightly movable joints; and diarthroses, or freely movable joints. Immovable and slightly movable joints are largely restricted to the axial skeleton. In general, fibrous joints are immovable, and synovial joints are freely movable. However, cartilaginous joints have both rigid and slightly movable examples.
