"The tympanic membrane is like a tambourine that has a leather flap on the outside that produces music when struck."
"The eardrum is stretched across the outer side of a bony, air-filled cavity called the middle ear. Just as the tympanic membrane is like a drum head, the middle ear cavity is like a drum bod"
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.
