Plural of ampulla; multiple small rounded flasks or vessels, especially the dilated anatomical structures found in the ear and reproductive systems.
From Latin ampulla, with the regular Latin plural -ae. This preserves the original Latin plural form used in anatomical terminology.
Scientists love keeping Latin plurals—we say 'ampullae,' not 'ampullas,' because medicine and biology deliberately maintain Latin to create universal scientific language that works across all countries.
