What's the difference between utricle and utriculus?
Utricle
Definition:

(n.) A microscopic cell in the structure of an egg, animal, or plant.
(n.) A small, thin-walled, one-seeded fruit, as of goosefoot.

Utriculus
Definition:
(n.) A little sac, or bag; a utricle; especially, a part of the membranous labyrinth of the ear. See the Note under Ear.
Example Sentences:
