nasal cavity
"nasal cavity is like violin body; its contribution to speech is a matter of resonance."
"Sinuses and Nasal Cavity, is like changing the car cabin air filter which is done once in a while. Get a kit at the drug-store which has a bottle with a head that you can shoot water with saline up there. The fleshy part just inside the corner of your eyes is part of the sinus and a booger will be stuck up at the top of that nasal cavity."
"The nasal cavity is like a little cave behind the nose. Air is warmed and moistened there. A thick sticky liquid called mucus coats the nasal cavity"

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
