The utricle, or utriculus (, diminutive of uter, meaning "leather bag"), along with the saccule, is one of the two otolith organs located in the vertebrate inner ear. The utricle and the saccule are parts of the balancing apparatus ( membranous labyrinth) located within the vestibule of the bony labyrinth (small oval chamber).
These use small stones and a viscous fluid to stimulate hair cells to detect motion and orientation. The utricle detects linear accelerations and head-tilts in the horizontal plane.
Utricle ( Latin: utriculus, diminutive of utur, meaning "leather bag") can refer to:
- Utricle (ear), a part of the inner ear
- Prostatic utricle, a small indentation found in the male prostate
- Utricle (fruit), a type of dry fruit similar to an achene
