"Epiglottis is like a traffic cop guiding food down the correct digestion road."
"The epiglottis is like a trap door at the back of our mouth. This trap door belongs to both the respiratory system and the digestive systems."
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.
