Utricle

The utricle is a specialized part of the inner ear involved in sensing changes in head position and motion, specifically detecting horizontal movements and the effects of gravity. It contains tiny crystals and hair cells that move when you tilt your head or move side to side. This movement sends signals to your brain to help maintain balance and spatial orientation. The utricle works together with other parts of the inner ear to help you understand where you are in space and keep your posture steady during daily activities.
