"These microvilli are like little hairs sticking out. They grab passing food particles and use enzymes to break them down so the food can be absorbed by the body."
"microvilli are like bristles on a brush"
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.
