Unlike the cochlea, which focuses on auditory transduction, the vestibular system is concerned with balance and spatial awareness. The human body relies on intricate systems to perceive the world and maintain balance, with the vestibular system playing a critical role in this silent orchestration.

These signals are sent primarily to the vestibular nuclei in the brainstem, where they are immediately integrated with visual and proprioceptive input. As the head turns, the inertia of the endolymph fluid inside the canals causes it to lag behind, bending the cupula and stimulating hair cells.
A thorough understanding of echo anatomy is vital for clinicians to differentiate between peripheral and central causes of dizziness, ensuring accurate diagnosis and management. When the head tilts or moves in a straight line, the weight of the otoliths causes the gel layer to shift, bending the stereocilia of the hair cells.

The bony labyrinth is divided into three distinct sections: the semicircular canals, which detect rotational movements; the vestibule, which serves as the central chamber; and the cochlea, which is responsible for hearing but shares the same fluid environment. These sac-like organs contain a specialized patch of hair cells covered by a gelatinous layer embedded with tiny calcium carbonate crystals known as otoliths.
