95. Articulations between the Anterior Ends of the 

 Ribs and the Sternum, Articulationes costo-sternales, 



anterior view. 



The articulations between the anterior ends of the ribs and the 

 sternum are found from the second to the seventh ribs; the cartilage 

 of the first rib is united directly to the Manubrium sterni (articulation 

 here extremely rare). Each of these articulations consists of a synovial 

 capsule, which is covered on the anterior surface by fibrous bands, Liga- 

 mcnta sterno-costalia radiata.
