Ampullae
Definition
An adapted plural form or old variant for ampullae / ampullate structures; in biology and comparative anatomy, it designates the sac-like structures, vascular dilations, or small muscular bulbs found within the semicircular canals of the inner ear or in the water-vascular system of echinoderms. Alternatively, in some old regional dialects, it represents a popular verb form derived from 'a ampula' (to bulge or structurally inflate).
