frontal

bone forming anterior cranium

zygomatic

cheekbones

maxilla

upper jaw

nasal

bony skeleton of nose

palatine

posterior roof of mouth

parietal

bone repair united by the sagittal suture

temporal

site of jugular foramen & carotid canal

sphenoid

contains a "saddle" that houses the pituitary gland

lacrimal

allows tear ducts to pass

palatine

forms most of hard palate

ethmoid

superior & medial nasal conchae are part of this bone

temporal

site of external auditory meatus

sphenoid

has greater & lesser wings

ethmoid

its "holey" plate allows olfactory fibers to pass

nasal

facial bone that contains a sinus

ethmoid, sphenoid, & frontal

three cranial bones containing paranasal sinuses

occipital

its oval-shaped protrusions articulate with the atlas

occipital

spinal cord passes through a large opening in this bone

hyoid

not really a skull bone

mandible

forms the chin

vomer

inferior part of nasal septum

maxilla & mandible

contain alveoli bearing teeth
