In cartilage joints, bones are joined by cartilage because small movements are possible in these joints, they are also called anfiartroses. There are two types of cartilage joints:
The bones of a synchondrosis-like joint are joined by a hyaline cartilage. Many synchondroses are temporary joints, with cartilage being replaced by bone over time (this occurs in long bones and between some bones in the skull). The joints between the first ten ribs and the costal cartilages are permanent synchondroses.
Post Cranial Synchondroses:
The joint surfaces of the symphysis-joined bones are covered by a layer of fibrous cartilage. Among the bones of the joint is a fibrocartilaginous disc, which is the distinguishing feature of the symphysis. Because these discs are compressible, they allow the symphysis to absorb impacts. The articulation between the pubic bones and the articulation between the vertebral bodies are examples of symphysis. During development the two halves of the mandible are joined by a midline symphysis, but this joint becomes completely ossified in adulthood.
