What are alveolar processes
sockets and supporting bones of the teeth
The maxillary bones form the floor of what cavities
orbit and nasal cavity
What 4 bones of the skull/face have sinuses and what are their purpose
frontal, maxillary, sphenoid and ethmoid
used to lighten the skull and serve as resonating chambers for speech
What part of the orbital wall do the zygomatic bones make
lateral
How can you identify the lacrimal bones

vomer
Besides the ethmoid bone what other bones form the turbinate
inferior nasal concha
What is the nasal septum and what structures form it
The vertical partition that divides the nasal cavity into L and R sides
-formed by vomer, perpendicular plate of the ethmoid, and the septal cartilage
Parts of what 7 bones form the orbits
Frontal, zygomatic, maxillary, ethmoid, sphenoid, palatine, lacrimal
