utriculus

A sac or pouch.

In anat., zoology, and botany, same as utricle.

The differences which are seen in it are partly due to the way in which the two cavities of the vestibule, the utriculus and sacculus, are connected together, and to the course taken by the semicircular canals which spring from the former.

A little sac, or bag; a utricle; especially, a part of the membranous labyrinth of the ear. See the Note under ear.
