bond of union between the bodies of the vertebrae, but, except 

 in old people, they are not directly attached to the bone. A 

 thin layer of encrusting hyaline cartilage coats the opposing 

 vertebral surfaces. 



Vertical and horizontal sections must be made through two or more of 

 the fibre-cartilages, in order that their structure may be displayed. 



Ligamenta Intertransversaria. The intertransverse liga- 

 ments are feeble bands which pass between the tips of the 

 transverse processes. In the lower part of the thoracic 

 region they are intimately blended with the intertransverse 

 muscles : in the middle and upper parts of the thoracic 

 region they entirely replace those muscles.
