neurotransmitter vesicles


Bang Goes The Nerve Cell

a: Neurotransmitter vesicles ~
b: battery of fireworks

What: "Loaded with the neurotransmitter acetylcholine, the vesicles are like a battery of fireworks poised to launch a neurotransmitter barrage into the synaptic cleft - where this amplified signal will in turn energize the adjacent muscle fiber. In the last step, what biologists call a "fusion event," the calcium ions trigger some of the vesicles to fuse with the cell membrane and open outward, allowing their payload to escape."

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.
