Sternal synchondroses
Synchondroses sternales
Definition
The sternal synchondroses are the cartilaginous joints between parts of the sternum, subdivided into three types of joints:
- Manubriosternal synchondrosis: the cartilaginous joint between manubrium and body of sternum. It is present in young domestic mammals, and in adults, only in carnivores, horses and sometimes in goats (in adult ruminants and pigs, the manubrium is joined to the body of the sternum by a synovial joint)..
- Intersternal synchondroses: cartilaginous joints between sternebrae. They may be ossified in pigs and ruminants.
- Xiphosternal synchondrosis: the xiphosternal synchondrosis is a cartilagionous joint between the body of sternum and the xiphoid process. It may be ossified in pigs and ruminants.
