Simulation of endolymph flow for response of cupula

Semicircular canal plays an important role in sensing of human body orientation. Cupula is the system in semicircular canal responsible for sensing rotational head movements. It is excited by the flow of endolymph caused due to inertia of head movement. There are various disorders related to semicircular canal, the most common disorder is Benign Paroxysmal Positional Vertigo (BPPV). Present work focuses on determination of response of cupula due to endolymph flow in the horizontal semicircular canal. Variation of pressure generated on cupula by endolymph for different rotational velocity of head is studied and reported. Response of cupula with appropriate boundary conditions is extracted. Results obtained open up new area of research in better understanding the behavior of cupula with endolymph flow. It may aid in the betterment of curing BPPV.
