Etymology: Latin "uter" meant a leather bag, most often a wineskin, and its diminutive "utriculus" meant a little bag or flask. English took that smaller form as "utricle," and "utricular" adds the suffix "-ar," meaning "of or relating to," so the word describes anything shaped like or working as a small sac. The image of a container holding liquid carries over to living things. Bladderworts, the carnivorous aquatic plants of the genus Utricularia, trap prey in small bladder-like sacs, and the genus name comes from the same Latin root. In the human ear, the utricle is one of the two sac-like chambers of the inner ear's vestibule that sense head position and linear motion, so "utricular" can describe structures in both plants and animals.
