smooth endoplasmic reticulum
"The smooth endoplasmic reticulum is like a mother. She goes through your room throwing away all of the bad stuff you have, provides you with sustenance, makes sure you drink your milk, and makes sure you have the energy to go outside and play."
"The smooth Endoplasmic reticulum is like the ninjas of the village because it contains enzymes that perform specialized tasks in the cell in the same way that the ninjas of the village perform specialized tasks in the form of missions for the village."
"The smooth endoplasmic reticulum is like the conveyor belts in the Chococella Chocolate Factory because the conveyor belts transfer chocolate to other parts of the factory. However, conveyor belts would not help produce the exterior building (membrane production)."

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.
