Temporal Course of
The temporal course of initiatives superiorly to articulate with the temporal bone, forming the zygomatic arch.
Maxillary Course of
The maxillary course of initiatives laterally and articulates with the maxilla, forming the lateral wall of the orbit.
Zygomatic Arch
The zygomatic arch is fashioned by the union of the zygomatic bone’s temporal course of with the temporal bone’s zygomatic course of. It offers assist for the cheek area.
The Mandible
The mandible, or decrease jawbone, is the one movable bone of the cranium. It consists of the next subparts:
Physique
The physique of the mandible varieties the principle portion of the jaw, supporting the tooth.
Ramus
The ramus is the ascending portion of the mandible and consists of the condylar course of and the coronoid course of.
