utricle
The utricle is a small, sac-like structure located in the inner ear, specifically within the vestibular system. It plays a crucial role in maintaining balance and spatial orientation. The utricle contains sensory hair cells that detect changes in head position and linear acceleration, helping the body understand its movement in relation to gravity.
In addition to the utricle, the saccule is another important structure in the vestibular system. Together, these two organs work to provide the brain with information about motion and balance. This information is essential for coordinating movements and maintaining stability while standing or moving.
