AETICULATIONS OF THE HEAD

InterspillOUS Ligaments (2, fig. 346). In the dorso-lumbar region 

 there is a series of short -flat layers of connective tissue passing in a 

 backward and downward direction from the posterior border of the superior

 it. In the cervical region they are composed of elastic tissue to allow 

 of a more extensive and free movement of the neck.

The articular processes of the vertebrae throughout are connected by 

 means of a capsular ligament, and the same may be said of the articulations 

 on the transverse processes of the two last lumbar and first sacral vertebrae. 



ARTICULATIONS OF THE HEAD 



It has elsewhere been pointed out that these are for the most part 

 immovable, and the mode of formation has been described. 



The Tempero-Maxillary Articulation (fig. 348) or joint formed 

 between the lower jaw and the temporal bone is an exception. 



Here the condyles on the superior part of the inferior maxilla fit into
