2

how many zygomatic bones

inferior orbital fissure

located between the maxilla, zygomatic bone, and the greater wing of the sphenoid

alveolar process

part of the maxilla that has eight teeth embedded in cavities along the inferior margin of this process.

nasal conchae

scroll shaped, thin and curved divide the nasal cavities into compartments to break the flow of air coming in through the nose

ramus

terminates in a "U" shaped notch on the mandible

optic foramen

the apex of the orbits corresponds with what?

septal cartilage

the cartilage anteriorly to the nasal septum is called

tempomandiublar fossa

the condyloid process fits into what on the temporal bone.

muscle attachments

mucous membrane

the nasal conchae cleans and warms the air as it comes in contact with the what?

mandibular notch

the notch at the end of the mandible

apex

the point of the orbit cone which is most posterior is called what?

base

the rim of the cone chapped orbits is called the what?

ethmoid bone

the superior and middle nasal conchae are formed from what bone

pterygoia plate

the vertical portion of the "L" palatine bone extend between one maxilla and what part of the sphenoid bone

mental point

the very center of the mentum

temporal bone

the zygoma connects with the zygomatic process of what side bone, making up the zygomatic arch which is easily broken

cheekbone

the zygomatic bones make up the lower portion of each orbit and form the prominent part of what boney landmark?

mental foramina

these are located on each half of the mandible which serve as passageways for nerves and blood vessels

lacrimal bones

these bones are the thinnest and most delicate bones in the body, associated with the tear ducts

nasal bones

these two bones form the bridge of the nose once fused together.

mandible

thin and horseshoe shaped, largest of the facial bones, the only movable bone in the adult skull

vomer

thin and triangular bone with the surface marked by small furrow like depressions for blood vessels.

maxillary bone

this bone articulates with all other facial bones

palatine bone

this bone is located internally, "L" shaped

cleft palat

this is a congenital defect in which the palatine bones don't unite

sphenoid strut

this is a small piece of bone which is a portion of the lateral wall of the optic canal

superior orbital fissure

this is an opening between the greater and the lesser wings of the sphenoid bone located lateral to the optic foramen

ramus

this is superior to the gonion of the mandible

gonion

this is the angle of the mandible located at c4

maxillary bones

this is the largest immovable bones in the face

TMJ

this is the only movable joint in the skull

symphysis menti

this is where the two bodes of the mandible unit at the midline

palatine process

this part of the maxilla form the roof of the mouth, hard or bony palate, only seen in an inferior view
