"Gliding joints are like two plates sliding across one another. Carpal bones of the wrist are an example of a bone forming a gliding synovial joint. Also known as planar joints, gliding joints allow a smooth movement in several directions over smooth surfaces."
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.
