utricle
Inner ear sac
A utricle is a small sac or bladder-like structure.
In anatomy, the utricle is one of two fluid-filled chambers in the inner ear that help detect head position and movement—the vestibular system's gravity sensors.
In botany, a utricle is a small, thin-walled fruit that doesn't split open when ripe, or the bladder-like traps on carnivorous plants like bladderworts.
