the maxilla forms 4 cavities of the faces what are they | the mouth,the nasal,one orbit & maxilla sinus |
each maxilla consists of what | a centrally located body & 4 processes |
the body lies what to the nose | lies laterally to the nose |
the frontal process projects how | upward toward along the lateral border of the nose towards the frontal bone |
the zygomatic process projects how | laterally to unite with the zygoma |
the alveolar process projects how | inferior aspect of the body of each maxilla(8 upper teeth) |
how is the anterior nasal sinus formed | 2 maxillae are united in the midline anteriorly |
how is the palatine process demonstrated | on a inferior view of the 2 maxillae |
the hard palate is know as | the bony palate |
the maxillae and the hard palate form what kind of joint | together they form a synarthrodial(immovable) joint |
a congenital defect,an opening b/w the palatine processes,caused by an incomplete joining of the 2 bones | cleft palate |
forms the posterior part of the hard palate | palatine bones |
only the horizontal portions of the L-shaped palatine bones are visible on this view | smv projection |
the palatine bones helps forms the | floor of the nasal cavity & the bottom & upper portion of the mouth |
what is the pterygoid hamuli | the feet of the sphenoid |
one zygoma is located lateral to the zygomatic processes of each maxilla,these bones are sometimes called | malar bones |
what makes up the zygomatic arch | maxilla,temporal & zygoma |
the zygomatic prominence is a positioning landmark & refer to what | the prominent portion of the zygoma |
each maxillae articulates with what | 2craninal bones,frontal & ethmoid,7facial bones zygoma,lacrimal,nasal,palatine,inferior nasal conchae,vomer,maxilla |
each zygoma articulates with | 3cranial bones,frontal & sphenoid,temporal,one facial bone maxilla |
what are the thinnest and most fragile bones in the entire body | rt & lt nasal & lacrimal bones |
the nasal bones are located | anterior on the medial side of each orbit |
the lacrimal bones are located | anterior to the frontal process of the maxilla |
forms the bridge of the nose | 2 fused nasal bones |
the nasal bones form what position point | the nasion |
does nasal bone & lacrimal bone touch? | they do not touch,are b/w the maxilla |
each lacrimal bone articulates with | 2 cranial bones,frontal,ethmoid,2 facial bones maxilla & inferior nasal conchae |
each nasal bone articulates with | 2 cranial bones,frontal,ethmoid,2 facial bones maxilla & adjacent nasal bone |
where is the rt & Lt inferior nasal conchae located at | lower 1/3 of the nasal seputum |
each nasal conchae articulates with | 1 cranial bone ethmoid,3 facial bones maxilla,lacrimal,palatine |
what forms the bony nasal seputm | the ethmoid & vomer-perpendicular plate of ethmoid & vomer bone |
vomer means what | plowshare |
lacrimal means what | tear |
the triangle shaped bone forms the inferoposterior part of what | the nasal seputum |
a deviated nasal seputum describes what | clinical condition where the nasal seputum is deflected or displaced laterally |
each vomer articulation with | 2 cranial bones sphenoid,ethmoid 4 facial bones rt & Lt palatine bones rt & lt maxillae,(nasal seputum also) |
at what age does the mandible join together | around one year of age |
what divides the mandible into two parts | the gonion/angle |
the body of the mandible is | anterior portion of the mandible |
the ramus of the mandible is | superior portion of the mandible |
how far does the alveolar process.ridge extends | the entire superior portion of the body |
what is the symphsis menti | the union of both sides of the mandible |
what is the mentum | the mental protuberance,a flat triangluar area below the symphysis |
what is the mental point | the center of the mental protuberance |
what is the mental foramina | serves as a passageway for nerves and blood vessels |
what is the ramus | the upper portion forms a u-shaped notch termed the mandibular notch. |
what is the coronoid process | the anterior end that does not articulate with another bone |
what is the condyloid process | the posterior process of the upper ramus |
the condyle has 2 parts what are they,what do they fit into | head & neck-will fit into the temporomandibular fossa |
what does the SMV shows | the mentum,body,coronoid process,ramus & condyle |
