A, Funicular or cordiform portion. B, Lamellar or flat portion. C, Attachments to dorsal spines. 

 Nos. 1 to 7, Cervical Vertebra. 



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 ti-ansverse processes of the two last lumbar and first sacral vertebrae. 



AETICULATIONS 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
