from the outside. 



The inferior maxilla is divided into the body and 2 rami. 



In the middle of the anterior surface of the body is the mental 

 protuberance, Protiiberantia mmtalls ; V further externally the mental 

 foramen. Foramen mentals, under which the external oblique line, Lima 

 obliqua cxtcrna, runs outward to the anterior border of the ramus. The 

 lower border is broad, the u p p e r divided into 16 alveoli, for 

 that number of teeth. The 2 rami ascend from the posterior end of 

 the body; their posterior border forms with the lower border of the 

 body, the a n g 1 e, Aiujulus maxillae. At the upper border there are 2 pro- 

 cesses separated by the sigmoid notch, Tnclsura scmilunaris ; the anterior 

 is the Processus coronoideus, the posterior the Processus condyloideus. The 

 latter has a constricted n e c k, Collum, and a h e a d, Capitulum, covered 

 with cartilage, for articulation with the glenoid fossa of the temporal bone.
