VERTEBEAL COLUMN 



47 



The arches of adjoining ver- 

 tebrre are joined by means of 

 cephalic and caudal articular 1 

 processes which project on each 

 side toward the head and toward 

 the tail, usually from the junction 

 of the pedicle and the lamina 

 (Fig. 17). The cephalic articu- 

 lar processes articulate with the 

 caudal articular processes of the 

 preceding vertebra, and the caudal 

 articular processes articulate with 

 the cephalic articular processes 

 of the succeeding vertebra. The 

 transverse processes spring from 

 the sides of the pedicles or from 

 the sides of the body, and are directed in the main transversely to the 

 long axis of the body. A few other processes are found on some

 cles are emarginate, producing the anterior or cephalic and posterior 

 or caudal intervertebral notches, which form with the similar notches
