sternokostalis
The sternokostalis, or sternocostal joints, are the articulations between the sternum and the costal cartilages of the ribs. They form a key part of the thoracic cage, linking the rib cage to the sternum and contributing to chest wall mobility during breathing.
The first sternocostal joint is a primary cartilaginous joint (synchondrosis) between the first costal cartilage and
Each sternocostal joint is surrounded by a joint capsule and reinforced by ligaments, notably the radiate sternocostal
The sternocostal joints are innervated primarily by the ventral rami of the intercostal nerves, providing sensory
Functionally, the sternocostal joints permit limited movements that facilitate rib elevation and chest expansion during inspiration.
