| what is the largest movable facial bones (in an adult) | mandible |
| 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 |
