The fibrous connective tissue is longer in these joints than in sutures or gomphoses, An example of a syndesmosis is the connection between the distal radius and ulna or the distal tibia and fibula, Examine an articu- lated skeleton in the lab and compare it to figure L2.2, Cartilaginous Joints If bones are held together by cartilage, the articulation is known as a cartilaginous joint.

Unformatted text preview: the cartilage is thin between bones, the joint is immov-able, Cartilaginous joints are known as s;rnchondroses (SIN-kon-DRO-sees) (singular, synchondrosrsJ. If the carti-Iage is long, there is more movement in the joint, In one case, the cartilaginous joint is a phase in the development of the skeleton, This is an immovable joint called the epiphyseal (EP-ih-FIZ-ee-ul) plate, which is illustrated in figure 12.3. This joint eventually fuses to form a single bone. Another example of a synchondrosis is the articula-tion between the true ribs and the sternum bv the costal ,f I _H f'"31:, i 'r.!
