25
Maxillae processes
Frontal process, zygomatic process, alveolar process, and palatine process "of maxilla"
26
What happens if the palatine process isnt fused together?
surgery (important for sucking)
27
What forms the other 1/4 of the hard palate?
palatine bone
28
Foramen located in the palatine process?
incisive foramen
29
What facial bone forms the cheek?
the zygomatic bone
30
What does the zygomatic facial bone articulate with?
Frontal, temporal, sphenoid, and maxillary
31
What forms the zygomatic arch
The temporal process of the zygomatic bone and the zygomatic process of the temporal bone
32
Location of the: orbital fissure
Between greater wing of sphenoid and the maxillae
33
What bone is superior to the orbital fissure?
lesser wing of the sphenoid
34
What is the infraorbital foramen?
Maxillary branch of trigeminal nerve
35
Where does the vertical part of the palatine bone ascend from?
Between the maxilla and pterygoid process of sphenoid
36
Nasal conchae purpose?
help filter air before it passes to lungs
37
What does the vomer bone form?
Forms the inferior portion of the bony nasal septum
38
What is the largest and only movable skull bone?
mandible
39
Mandible is made up of:
ramus (vertical), body (horizontal), and angle (gonion)
40
Landmark: C3
Mandible angle / gonion
41
What process is located in the ramus of the mandible?
coronoid
41
What forms the TMJ
The mandibular condyle articulates with mandibular notch of the zygomatic process of the temporal bone to form Temporomandibular joint (TMJ)
42
Mandibular notch is located between ________
the mandible condyle and coronoid process
43
Tip of chin is called _______
mental point
44
What foramen is located in the mandible?
mental foramen
45
What is the term for moving the mandibular condyle? (open mouth position)
Excursion
46
What type of joint is the TMJ?
gliding / hinge
47
To view the TMJ, how are images acquired?
with mouth open / closed
48
What forms the circumference of the orbit?
frontal, zygomatic, maxillary
49
What forms the roof of the orbit?
Frontal bone (orbital plates), lesser wing of sphenoid
50
What forms the floor of the orbit?
Maxillary, zygomatic, palatine (blow out fractures occur here-bleeding/fluid into maxillary sinus)
51
Medial wall of orbit consist of?
maxillary, ethmoid, lacrimal - thinnest part
52
Lateral wall of orbit consist of?
frontal process of zygomatic, greater wing of sphenoid - thickest part
53

61
Tip of the projection above acanthion
anterior nasal spine
