In a synchondrosis, the connecting material is hyaline cartilage. An example is the junction of the epiphysis and diaphysis of a long bone. In this case, the connecting material is called the epiphyseal plate.
Synchondoses are immovable joints.
In symphysis joints the ends of the articulating bones are covered wit hyaline cartilage. Between the bones , however, there is a broad flat disc of fibrocartilage. An example is the joint between the manubrium and the body of the sternum.
