"Each hormone is like an arrow shot from a bow - it's aimed at a target organ or group of cells. When it hits its target, a 'score' or effect is achieved."
"A hormone is like a chemical messenger. It is made in one part of the body (in this case, the pancreas) and is secreted (usually) into the bloodstrea "
"The endocrine system - the group of organs and glands responsible for releasing hormones that regulate key bodily functions - is sometimes compared to an orchestra. Each hormone is like an instrument. Playing together, in tune, they sound amazing. But what happens if, right in the middle of a concert, a violin suddenly goes wildly astray, twanging on its own? And then a clarinet starts shrieking? And then the pianist can't keep up? The music would sound like crap, right? "
"Every cell in the body contains receptors-essentially tiny locks-on its surface. A hormone is like a microscopic key floating in the bloodstream: When it finds a matching lock, it binds to the receptor and triggers the cell to do something, such as grow or divide."
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.
