Fig. 78*. 156 • LIGAMENTS OF THE PELVIS. The anterior costo-sternal ligament is a thin band of ligamentousfibres, that passes in a radiated direction from the extremity of thecostal cartilage to the anterior surface of the sternum, and inter-mingles its fibres with those of the ligament of the opposite side andwith the tendinous fibres of origin of the pectoralis major muscle. The posterior costo-sternal ligament is much smaller than the ante-rior, and consists only of a thin fasciculus of fibres situated on theposterior surface of the articulation. The superior and inferior costo-sternal ligaments are narrow fas-ciculi correspondiltg with the breadth of the cartilage, and connect-ing its superior and inferior border with the side of the sternum. The synodal membrane is absent in the articulation of the first rib,its cartilage being usually continuous with the sternum ; that of thesecond rib has an interarticular ligament, with two synovial mem
