Hair cells in the vestibular system are slightly different from those in the auditory system, in that vestibular hair cells have one tallest cilium, termed the kinocilium. Bending the stereocilia toward the kinocilium depolarizes the cell and results in increased afferent activity .

The hair cells and innervating neurones associated with the vestibular organ are very vulnerable to degeneration, which increases with age. In fact, approximately 35% of the United States population aged 40 or over are affected by some form of vestibular system disorder and the consequences can be devastating.

Many questions remain regarding the hair cell ribbon synapse, and this system will certainly be a focus of productive research activity for many years to come. Another specialized synapse is found in Type I vestibular hair cells, which are surrounded on the basolateral side by a calyx-like expansion of the primary afferent nerve ending . The peripheral processes of vestibular ganglion cells comprise the nerve fibers that receive the stimuli from the hair cells of the otolithic organs and semicircular canals, respectively. The central processes of the vestibular ganglion comprise the fibers of the vestibular portion of the vestibulocochlear nerve (CN VIII). The peripheral sensory components of the vestibular system include the hair cells and structures that enclose those cells, the semicircular canals and the otolithic organs, the saccule and utricle.

The GFP+ cell expresses Gfi1 and overall has a normal appearance for a hair cell, except for a thin foot-like projection that extends to the basement membrane. Also in view are two support cells, one of which is directly next to the hair cell. Dimensions in μm (w x h x d) – 43.3 x 52.6 x 13.0.

Each vestibular structure of the membranous labyrinth has a region of epithelial lining that has become specialized into a set of secondary receptor cells (see Chapter 7) called hair cells (Figure 11-2).These hair cells form the basis of a sensory receptor organ within each vestibular structure. Efferent circuits within the nervous system carry nerve impulses from the central nervous system to sensory end organs.

Kinocilia transmit movement of the overlying otoconial membrane mass and cupula to the mechanotransducing portion of the hair cell bundle. Hair cells are the sensory receptors of both the auditory system and the vestibular system in the ears of all vertebrates, and in the lateral line organ of fishes. Through mechanotransduction, hair cells detect movement in their environment.
