"Synovial fluid is like egg white and covers the cartilage in the joint to facilitate smooth movement and keep it healthy."
"Synovial fluid is like a clear and slippery water that's full of lipids (essential fats) and proteins, which cushion the cartilage, allowing the joints to move effortlessly."
"Synovial Fluid is like the oil to the squeaky hinge on the door, it allows for the joints to move painlessly rather than making the bones rub against each other."
Yeah, that's it.
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.
