Section 2

Question Answer
How many facial bones are there?14
All facial bones can be seen on frontal and lateral views except how many?3; 2 palatine and vomer
What is the purpose of facial bones?help create cavities and orbits, give shape and form to the face
How many pairs and how many single facial bones are there?6 pairs 2 single
R/L maxillary boneslargest immovable bones on the face, unite below the nose
What 3 cavities does the maxillary bone help form?nasal, orbits, and oral
Frontal process of maxillary bonemost superior, articulates w/ frontal bone
Zygomatic process of maxillary bonearticulates w/ zygoma
Avelar process of maxillary boneabove top teeth, where upper teeth are embedded
Palatine process of maxillary boneanterior part of roof of mouth
Acathionlandmark, where nose meets upper lip
Body of maxillacontains maxillary sinus
maxillary sinusair filled, where all sinuses connect with nasal cavity
When all sinuses connect with nasal cavity it is called _________paranasal sinuses
Maxillary bones articulates with _________Frontal, ethmoid, zygoma, lacrimal, nasal, palatine, inferior nasal conchae, vomer, and other maxilla

Section 3

Question Answer
What makes the palatine process?the 4 processes of the maxilla
What forms the hard/ bony palate on the palatine process?anterior portion of the roof of the mouth
Where the right and left palatine process unite in the middle what type of joint is it?synarthrodial
What is cleft palate?when there is separation between the palatine process in the middle
Posterior part of the hard palate is the ___palatine bones
Palatine bones articulates withsphenoid, ethmoid, maxilla, inferior nasal conchae, vomer, and other palatine

Section 4

Question Answer
what do the zygomatic bones make?cheeks and lower portion of each orbit
What is another name for the zygomatic bones?malar bones
zygomatic archzygoma and zygomatic process of temporal bone
zygomatic prominenswhere cheekbones stick out
What does the zygomatic bones articulate with?frontal, temporal, sphenoid, and maxilla

Section 5

Question Answer
What are the thinnest and most fragile facial bones?lacrimal and nasal bones
R/L nasal bonesforms bridge of nose, makes the nasion
Nasal bones articulate with frontal, ethmoid, maxilla, and other nasal
R/L lacrimal bonesenclose tear ducts, on medial side of each orbit
Lacrimal bones articulate withfrontal, ethmoid, maxilla, inferior nasal conchae
Nasioninferior to glabella, where nasal bone meets frontal bone

Section 6

Question Answer
Inferior nasal conchaeindividual facial bone, come from lateral walls of the nasal cavity and extend medially
Inferior nasal conchae articulates withethmoid, lacrimal, maxilla, palatine
What are the 3 pairs of nasal conchae?superior and middle pairs, inferior pairs
What is the bony nasal septum formed by? perpendicular plate of ethmoid and vomer
vomermakes lower part of bony nasal septum, contributes to nose bleeds
Vomer articulates withsphenoid, ethmoid, palatine, maxilla
Mandiblelargest of all facial bones, only movable bone in adult skull
Infant mandible2 bones, form around 1 year of age
Gonion of mandible angle of mandible
Large U shape of mandiblemandibular notch
What is in the mandibular foramen?nerves
Where are the lower teeth rooted in the mandible?in the alveolar process of the body of the mandible
Symphysis mentiWhere mandible unites, middle of chin

Section 7

Question Answer
What does SMV stand for?submentovertex
What is SMV?best way to see the entire mandible
What forms the TMJ?condyloid process of mandible fitting into temporomandibular fossa of temporal bone
TMJ is located _________ and slightly _________ to the EAManterior and superior
When the mouth is open where does the condyle move?front edge of the fossa
When the mouth is closed where does the condyle move?in the fossa

Section 8

Question Answer
What type of joint is the TMJ?Synovial, diarthrodial, bicondylar, plane/gliding
What type of joint is the sutures of the skull?fibrous, synarthodial
