The horseshoe shaped Mandible consists of a horizontal body and an ascending ramus on each side. At the body of the mandible, the tooth-bearing alveolar part rests on the well developed lower part (base of the mandible). The mandibular ramus arises from the body of the mandible at the angle of the jaw (mandibular angle). The angle of the jaw provides outer and inner attachment sites for the masseter and the medial pterygoid, respectively. The ramus divides at its upper end into an anterior pointed muscular process (coronoid), and a posterior articular process (condylar), which bears the articular condyle (head) and slender neck of the mandibular. Between the two processes is the Mandibular Notch. The Zygomatic Arch is inserted between the maxilla, temporal, and frontal bones. Its temporal process adjoins the zygomatic process of the temporal squama at the temporozygomatic suture and forms the zygomatic arch.
