WebThe structure of the otolith organs makes them especially sensitive to movements like linear acceleration and head tilts. The vestibular system uses this information about movement obtained via the semicircular canals and otolith organs to maintain balance, stability, and posture; one way it does this is through its involvement in reflex actions. WebThe activation of hair cells occurs when their cilia are bent by the moment of endolymph. The semicircular canals sense the angular momentum. When we change the position of head, the endolymph lags behind, and pushes the cupula forward, in the opposite direction of the angular movement. This result in the activation of hair cells ...
WebEndolymph is the fluid contained in the membranous labyrinth of the inner ear. The major cation in endolymph is potassium, with the values of sodium and potassium concentration in the endolymph being 0.91 mM and 154 mM, respectively.

WebEndolymph is the name of the fluid that can be found in the canals. Because of inertia, the head rotates, which causes the endolymph to lag behind, which in turn causes the cupula to bend. Mechanoreceptors on the cupula are activated when the cupula is bent; these mechanoreceptors generate neural signals, which are then transmitted to the brain. WebHair cells. -Hair-like projections on the top (different looking neurons, highly specialized) -Play a role in both balance and hearing. -A lot of similarities in how the vestibular system and auditory systems work. At the neural level, they work in very similar ways once you get to the hair cells. Transmitting motion (vestibular system)

WebThe mechanical vibrations of the stapes footplate at the oval window creates pressure waves in the perilymph of the scala vestibuli of the cochlea. These waves move around the tip of the cochlea through the helicotrema into the scala tympani and dissipate as they hit the round window.
