Synchondrosis

From Wikipedia, the free encyclopedia
(Redirected from Synchondroses)

A synchondrosis (or primary cartilaginous joint) is a type of cartilaginous joint where hyaline cartilage completely joins together two bones.[1] Synchondroses are different from symphyses (secondary cartilaginous joints), which are formed of fibrocartilage, and from synostosis (ossified junctions), which is the fusion of two or more bones. Synchondroses are immovable joints and are thus referred to as synarthroses.are all synchondroses synarthrotic/immovable[citation needed]
