Synchondrosis

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. Synchondroses are immovable joints and are thus referred to as synarthroses.are all synchondroses synarthrotic/immovable^{[citation needed]}
