Vestibular neuritis, often viral in origin, inflames the nerve itself, causing prolonged imbalance. Often overlooked, the complex anatomy of echo, or vestibular, structures provides the foundation for our sense of spatial orientation and equilibrium.
Echo Anatomy Vestibular Pathways Explained: How Structure Impacts Balance and Spatial Orientation
Benign paroxysmal positional vertigo (BPPV) occurs when otoliths dislodge and migrate into the semicircular canals, triggering brief but intense episodes of dizziness. 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.
It achieves this through the detection of linear acceleration and angular rotation, sending constant signals to the brain about the body's position in the environment. 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. The Utricle and Saccule in the Vestibule Within the vestibule, the utricle and saccule act as gravity and linear motion sensors.
