Many Little Muscles Twitching Away

a: Sarcomere ~
b: a microscopic muscle

What: "Trigger points, more commonly known as muscle knots, are a patch of super-contracted muscle "sarcomeres." Muscles are made of millions of sarcomeres. A sarcomere is like a microscopic muscle: a little bundle of protein fibres that contracts. When a small section of sarcomeres goes into spasm, that's a trigger point."

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.
