descending axon of the bipolar cell
" The descending axon of the bipolar cell is like a thin pipe with narrow space trafficking many neuroactive substances and cell organelles from the soma to the axon terminal and in reverse. Perhaps this produces a requirement for short ribbons that will not impede microtubular transport. In contrast, axon terminal ribbons in sublamina b are located in a relatively spacious terminals packed with synaptic vesicles."
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.
