deep fossa continuing on to the ramus, the coronoid fossa, or 
masseteric fossa (¢). 
The medial surface (Fig. 37) is smooth and has near its 
caudal end a foramen, the mandibular foramen (/), which

communicates with the mandibular canal leading lengthwise 
through the bone to the mental foramen. The cranial end is 
roughened for attachment to the bone of the opposite side. 
The ventral border is smooth and rounded; it ends caudally 
in a blunt point, the angular process (¢). The dorsal 
(alveolar) border is slightly curved and bears the sockets 
(alveoli) for the teeth. It is continuous with the cranial margin 
of the coronoid process. 
The ramus is divided into two portions, the coronoid process 
(2) and the condyloid process (2). The coronoid process (4) 
extends dorsocaudad as a thin plate of bone with smooth sur- 
faces and borders. Its outer surface is partly occupied by the 
coronoid fossa (¢). The condyloid process (¢) has the form of
