Examples
- The utriculus is a small pouch found in the vestibular system of the inner ear, playing a crucial role in balance and spatial orientation.
- In the utriculus, sensory hair cells are embedded in a gel-like substance that detect movement and changes in acceleration.
- Each utriculus receives input from three semicircular canals and combines this information to help the brain maintain balance and posture.
- The utriculus and sacculus are two otolith organs in the vestibular system responsible for detecting linear acceleration.
- Damage to the utriculus can result in balance disorders, such as benign paroxysmal positional vertigo, which can cause brief but intense episodes of dizziness.
