Study Notes
Posterior Border (Back Wall)
- The upper back 3 sides are bordered with a number of cranial bones including the Maxilla, Ethmoid bone, Palatine bone, Sphenoid bone, Lacrimal bone as well as the interior concha.
Floor
- Apart from keeping the nasal cavity separated from the oral cavity, the hard palate, formed by the palatine process of the maxilla & the palatine bones (horizontal plates) also make up its smooth floor.
- The nasal & oral cavities are connected with each other through the nasopharynx (at the back of the throat).
- The soft palate & uvula (the fleshy projection at the back of the throat) together move up to close off this connection during eating to prevent food from entering the nasal cavity.
