| Sph. GREATER wing sphenoid | external, visible portion of the sphenoid bone |
| Sph. orbital surface of sphenoid | portion on the sphenoid behind each eye socket/orbit |
| Sph. foramen ovale | large, elliptical opening in inf. srf. which provides a passageway for mandibular nerves |
| Sph. foramen spinosum | opening in inf. surf. slightly post. & lat. to foramen ovale; passageway for small branches of mandibular nerves & meningeal blood vessels through the skull |
| ethmoid bone | loc. on the med. surf. of each eye socket; forms a portion of the root of the nasal cavity & closes the ant. portion of cranium |
| Eth. perpindicular plate | loc. on the inf. portion of the ethmoid; extends vertically downward on the midline; forms the sup. portion of nasal septum |
| Eth. nasal septum | the division b/t nostrils |
| Eth. sup. & middle nasal conchae | lat. to the perpindicular plate; provides reinforcement for the walls of nasal openings (nostrils) |
| occipital bone | loc. on the post./inf. surf.; most post. cranial bone |
| Occ. lamboidal suture | lies b/t occipital & both parietal bones |
| Occ. foramen magnum | large opening in inf. surf.; passageay for the brain stem |
| Occ. occipital condyles | 2 rounded processes in inf. surf.; 1 on each side of foramen magnum; articulates w/ 1st vertebra on the vertebral column |
| Occ. condyloid canal | small opening post. to occipital condyles |
| Occ. hypoglossal canal | provides passageway for spinal accessory & cranial nerves; passes through occipital condyles |
| Occ. median nuchal line | raised ridge of bone the extends vertically along midline on post. surf.; crosses over sup. & inf. nuchal lines |
| Occ. inf. & sup. nuchal lines | raised ridge of bone that extends horizontally across post. surf.; serves as pt. of attachment for post. neck muscles |
| maxilla | 2 bones; upper jaw; forms roof of mouth; 16 permanent teeth |
| Max. median palatine suture | runs along midline of roof of mouth |
| Max. palatine process of maxille | "hard plate"; ant. hard portion of roof |
| Max. alveolus | each individual tooth socket |
| Max. alveolar process | ridge of bone the forms the gums |
| Max. infraorbital foramen | small opening below each eye socket; nerves & bloods vassels run through |
| Max. anterior palatine foramen | ant. portion of hard palate; ant. end of median palatine suture |
| Max. transverse platine suture | runs horizontally along post. surf. of the palatine process of the maxilla/hard palate; perpindicular to med. palatine suture |
| palatine bones | 2; directly post. to palatine process of the maxilla/ hard palate; "soft palate" |
| Pal. greater palatin foramen | single larger opening |
| Pal. lesser palatin foramen | paired smaller openings |
| zygomatic bones | 2; forms ant. promenence of each cheek bone; inf. & lat. to each eye socket |
| Zyg. zygomaticofacial foramen | only opening on zygomatic bone |
| lacrimals | 2; b/t ethmoid & upper portion of maxilla; serves as the passageway for tear ducts |
| nasal bones | 2; forms top bridgee of nose; 2 thin rectangular bones |
| vomer | 1; loc. w/in the nasal cavity on the midline; makes up lower portion of nasal septum |
| inferior nasal conchae | 2; curved sections of bone that make up lateral walls of nasal openings (nostrils); directly below middle nasal conchae |
| med. -> lat. order | nasal, maxilla, lacrimal, ethmoid |
