ATLAS AND DENTATA. 51 



Spinous. — The spaces between the processes are filled by the 

 inter -sinnal liganierits. In the back they are triangular, in the 

 loins quadrangular, and in the neck deficient or wanting. The free 

 edge of the ligament is thick and cord-like.^ 



Ligamentum Nuchce. — Continuation of the last, reaching from 

 the seventh cervical vertebra to the vertical ridge on the occiput. 



Yelloiv Ligaments are between the bony bridges of the vertebrae 

 — twenty-three pairs ; the first is between the second and third 

 vertebrre. They are remarkable for their elasticity and colour. 



ATLAS AND OCCIPUT. 



Anterior L,iganient is a strong, broad ligament, extending from 

 the superior edge of the anterior arch of the atlas to the basilar pro- 

 cess of the occiput. The middle portion connected with the tubercle 

 of the atlas is thick. 



Posterior Ligo.rnent^ is thin, broad and loose, extending from the 

 posterior arch of the atlas to the corresponding edge of the foramen 

 magnum occipitis. It is perforated by the vertebral artery. 



Capsular Ligament surrounds the superior oblique process of the 

 atlas and the condyloid process of the occiput. Thicker and stronger 

 in front. 



ATLAS AND DENTATA. 



Transverse Ligament stretches across the atlas from one tubercle 

 to the other, dividing it into two 

 rings,3 (Fig. :33), and has an ap- ■^'^- ^^• 



pendix above,^ connecting it with 

 the occiput, and one below,* con- 

 necting it with the dentata. 



Moderator Ligaments are short 

 and thick ; extending from the sides 

 of the apex of the processus den- 

 tatus^ to a fossa on the inner side 

 of each condyle. They limit ro- 

 tation of the head. 



Middle or Straight Ligament, 

 reaches from the tip of the apex of the processus dentatus to the an- 

 terior edge of the foramen magnum. 



Capsular Ligament of the oblique process of the atlas and den- 

 tata is very loose. 



La,certi Ligamenlosi are ligamentous bands extending from the 

 occiput to the posterior part of the body of the dentata. 



LIGAMENTS OF THE PELVIS. 



Sacro- Iliac Symphysis. — The articular surfaces are covered by 

 cartilage and united by short, thick, strong fibres, which are with dif-
