A joint, as in children, where the bones are linked by cartilage, before the cartilage has changed to bone.
Joint in which the surfaces are connected by a cartilage plate.
A slightly movable joint in which the surfaces of the bones are separated by hyaline cartilage, as occurs between the ribs and sternum. This cartilage may become ossified in later development, as between the epiphyses and shaft of a long bone.
An immovable joint having surfaces between the bones connected by cartilages. This may be temporary, in which case the cartilage eventually becomes ossified, or permanent.
A joint where the surfaces are linked by cartilage growth.
