(ii) Syndesmosis (Figure 21.3 B). The bone margins are held together by dense collagenous fibers or by ligaments, and a somewhat greater amount of motion is allowed, (e.g. the lower ends of tibia and fibula, or radius to ulna).

(iii) Synchondrosis is a cartilaginous joint in which the connecting cartilage is converted into bone. Thus, it is a temporary joint. (e.g., epiphysis and diaphysis of long bones). The resulting bony joint is called synostosis, which is an immovable joint.

(iv) A permanent cartilaginous joint is present at the rib-sternum junction.
