Hydrodynamic Analysis of Endolymph in Semicircular Canals in a Transversal Head Rotation Using Finite Element Method

摘要

Vestibular system is a biosensor accelerometer in inner ear of human body which detects motion and spatial position of body. Human's brain can use the output information of this system to control muscles. Today, a sensor with ability to detect spatial position in some special conditions or to decrease errors can be helpful. In this paper, by studying some mechanisms and hydrodynamic parameters in the phenomenon of interactions between vestibular systems and eye muscles (VOR: Vestibule-ocular reflex) an effort was made to simulate a rotation of head in transverse plane. Thus, finite element method was applied. This can help us to describe the relationship between the kinematic features of head movement and mechanical characteristics of endolymph as a fluid. This relationship can explain the movement of head in a simple rotation. In this paper, angular velocity of head movement in a horizontal rotation is approximated for each amount of pressure at the exit of a semicircular canal. In conclusion, using these numerical data can make an application of this system in industrial devices, possible.
