(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.
