Synchondrosis
A synchondrosis is a type of cartilaginous joint where hyaline cartilage completely joins together two bones. Synchondroses are different from symphyses, which are formed of fibrocartilage, and from synostosis, which is the fusion of two or more bones. Synchondroses are immovable joints and are thus referred to as synarthroses.
Examples in the human body
Permanent synchondroses
- first sternocostal joint
- petro-occipital synchondrosis
Temporary synchondroses (fuse during development)
- epiphyseal plates
- apophyses
- synchondroses in the developing hip bone composed of the ilium, ischium and pubis
- spheno-occipital synchondrosis
