398 THE ANATOMY oF TJIK IIORSE 



Thf fiii/}m-spitioiig I'ujniii^nt consists of small toiiiprcssed buntlles of lon<,'i 

 tiidinul fibres, extoiuling fn)in the hist cervical spine to the spine of the 

 anterior coccygeal bone, and thus forms a continuous cliain. 



Thf interspinal Hytiminits consist of fibrous plates, filling up the spaces 

 between the spines, and attached before and behind to their opposite Iwrders. 

 One set of tliese fibres passes from the anterior border of one spine to the 

 posterior border of the one before it, taking a direction from below, forwards 

 and upwaitls ; another set runs from tlie posterior border of the spine to the 

 anterior bonier of that situateil behind it, taking a direction from below, 

 upwards and backwards. 



TnK ARCHES OR PLATES are connected together by tlie ligamenta vcrtebi;i- 

 tuni subtlava. These ligaments consist of yellow and white fibrous tissue. 

 Their attaclmient extends from the roots of the oblique processes to the origin 

 of the spinous processes. Their anterior edges are attached to the posterior 

 edges of the vertebral plates wliich are in front. Their posterior edges are 

 attached to the anterior edges and inferior faces of the plates which are

behind. Tlie ligamenta subflava do not exist between the occiput and atlas, 

 or between the athvs and dentata. 



Inter-transverse LIGAMENTS are situated between the transverse processes, 

 running from the transvei*se process of one vertebra to the same process of 

 the one next to it. 



The oblique processes are united by synoWal capsules one to the 

 other. These capsules, throughout the vertebraj of the back, are pro- 

 tected by wliite fibrous tissue, but in the cervical region the fibres 

 covering the capsules are yellow and elastic, and on this account, and 

 owing to the size of their arthrodial surfaces, latitude of movement is 

 permitte<l to a greater extent than is noticed in any other vcrtebi-al 

 region.
