sacculus
Tiny vestibular pouch
The sacculus is a small sac-like structure, particularly one of two fluid-filled chambers in the inner ear that helps detect gravity and linear acceleration.
Along with the utricle, it forms part of the vestibular system responsible for balance and spatial orientation.
The term appears in anatomy and biology for various small pouches or sacs in organisms.
