Synovial Sacs.~Theve is one sac on each side of the interarticular ligament. There is only one sac for the first costo-central joint. CosTO-TBANSVBHSE JoiNT. This ia maintained by two hgaments-an anterior and a posterior costo-transverse ligament, and it possesses a synovial Fig. 14. Two COSTO-VERTEBRAL, AND TWO INTERVERTEBRAL JOINTS, VIEWED FROM ABOVE.

The Posterior Costo-transverse Ligament is composed of a band of fibres stretching across the joint behind, and fixed by its extremities to the rib and transverse process. The Anterior {Interosseous) Costo-transverse Ligament stretches between the antero-inferior aspect of the transverse process and the neck of the rib. It is partly concealed by the transverse process, and is best seen when viewed from above and in front. Synovial Sac.—This will be exposed by removing the posterior costo- transverse ligament. In the last two or three ribs there is no separate synovial sac for the costo-transverse joint; but the posterior costo- central sac is extended over it, the two articular surfaces being in these ribs Please note that these images are extracted from scann
