- Nasal bones
-
meet at midline and form part of the bridge of the nose
mostly cartilage - Maxillae
-
articates with every facial bone except mandible
forms floor of orbital - Infraorbital foramen
-
an opening to the maxillae inferior to the orbit
infraorbital nerves and vessels passes through here - Alveolar processes
- an arch that contains the alveoli(sockets) for the upper teeth
- Palatine process
- It forms hard palate by this and horizontal plate of the palatine bone
- Maxillary sinuses
- empities into nasal cavity
- Temporal process
-
projects posteriorly
articulates with the zygomatic process of the temporal to form the zygomatic arch - Body
- curved, horizontal portion of the mandible
- Ramus
- two perpendicular portions of the mandible
- Angle
- Where each ramus meets with the body of the mandible
- Condylar process
-
Post. to ramus
articulates with the mandible fossa and articulates with the tuberlce of the temporal bone to form temporomandible joint - Mandibular notch
- a depression btwn. the coronoid and condylar processes
- Alveolar process
- an arch containing the alveoli for the mandibular (lower) teeth
- Mental Foramen
- inferior to the second premolar tooth.
- Mandibular foramen
-
Medial surface of each ramus
often used to inject anethetics
