Vestibular Hair Cells
Vestibular hair cells are sensory receptors located within the fluid-filled vestibular organs (the utricle, saccule, and semicircular canals) of the inner ear. Similar to the hair cells in the auditory system, they are stimulated by fluid movement. However, vestibular hair cells specifically respond to gravitational forces and head movement, subsequently transmitting signals to the brain through the vestibular nerve.
