Classifying Joints The intricate movements of a human, such as those performed in dance and athletics, are  accomplished by using a wide variety of joints. Though joints enable the skeleton to be dynamic,  they also play an important role in stability and protection. In fact, the mobility of a joint is often  inversely proportional to its stability. For example, the sutures of the bones of the cranium are  basically immovable in relationship to one another, but due to their stable nature, they serve to  protect the brain throughout daily life and during incidents of trauma. On the other hand, the ball-and-

Unformatted text preview: socket of the shoulder enables a wide variety of complex movements. This increase in the amount of mobility leads to instability, which is why the shoulder is susceptible to injury. A joint (articulation) occurs wherever bones meet. Joints are classified both structurally and functionally, as shown in Table 1. Table 1. Joint Classification Functional Class Structural Class Joint Description Type Example of Joint synarthrosis (immovable) fibrous suture interlocking seams between cranial bones synarthrosis (immovable) fibrous gomphosis peg-and-socket joint between teeth and sockets...
