(§ 250, B) ; while still moist the two rami were slightly separated 

 at the symphysis menti, and the teeth of the right side were 

 extracted with the nippers to show the alveoli, as in Fig. 57.

§ 559. Alveoli. — Tbese are the cavities in which the teeth are implanted. 



§ 560. Cd. (Condylus) mandibularis — Mandibular condyle or arthral head. — This 

 smooth cylindrical process articulates diarthrodially with the Fossa mandibularis of the 

 temporal (Fig. 57). 



D. m., Dens molaris. — Molar tooth. 



DD. pm., Dentes praemolares. — Praemolar teeth. 



D. c, Dens caninus. — Canine tooth ; Wilder, 13. 



DD. i., Dentes incisores. — Incisor teeth. 



Fm. di., Foramen dentale inferior. — Inferior dental foramen. 



Margo alveolaris — Alveolar margin. — The margin or border of the jaw in which the 

 teeth are implanted. 



Pre. (Processus) coronoideus. — Coronoid process. 



§ 561. Symphysis menti. — The symphysis is the amphiarthrodial articulation be- 

 tween the two rami. It is indicated in the figure by a dark line just to the left of the 

 incisor teeth. In old cats this symphysis often becomes anchylosed, but in young individ- 

 uals considerable motion is possible between the two rami.
