The cupula is a structure in the vestibular system, providing proprioception ( pertaining to the sensations of body movements and awareness of  Present work focuses on determination of response of cupula due to endolymph Keywords: semicircular canal, vestibular system, endolymph, cupula, BPPV. New theoretical results detail the velocity field in a fluid boundary layer surrounding the cupula. The governing equations were linearized for small perturbations  The ampullary cupula is a gelatinous body overhanging the hair cells of the ampullary crests of the semicircular ducts; sensory hair cells are immersed in it and  1 - Ampulla mit innen liegender Cupula, 2 - Knöcherne Bogengänge, Zum Beispiel, wenn der Vestibular-Apparat defekt ist wie beim Morbus Menière, wenn es  9.

Any dysfunction of vestibular system leads to various diseases, the most common among them is Benign Paroxysmal Positional Vertigo (BPPV). BPPV is most found in elderly people causing vertigo/dizziness which leads to fall and serious injuries.

The cupula, a thin vane, sits atop this crest, filling the lumen of the semicircular duct. The stereocilia of the hair cells are embedded in the gelatinous cupula. By pressing the "play button" in Figure 10.1, the animation will show the effects of head rotation. The slow return is a function of the elasticity of the cupula itself.

However, the cupula buried in the semicircular canals (SCCs) will be destroyed if it is detached from the The crista contains hair cells with stereocilia oriented in a consistent direction. The cupula, a thin vane, sits atop this crest, filling the lumen of the semicircular duct. The stereocilia of the hair cells are embedded in the gelatinous cupula.
