93. Articulations between the Posterior Ends of 

 the Ribs and the Vertebrae, Articulationes costo-spinales, 



anterior view. 



Between the heads of the ribs and the articular fossae of the 

 vertebral bodies are articulations, Articulationes costo-vertebrales, surrounded 

 by a capsule, and covered by the Ligamentum capituli costae anterius (anterior 

 costo-vertebral). When the head of the rib has two articular facets 

 (second to tenth ribs), the articular cavity is divided by the Ligamentum 

 interarticularc (continuation of the intervertebral disc to the Crista capituli) 

 into two parts. The articular cavity of the eleventh and twelfth ribs is 

 always single, that of the first rib usually single; sometimes, when the 

 articular fossa is formed by the seventh cervical and first dorsal vertebrae, 

 double, divided by a Ligamentum interarticulare.
