Summary Introduction

Introduction:

The equilibrium is maintained by two structures, which are present in the inner ear. These structures are vestibules and the semicircular canals. The ears have three semicircular canals, which are filled with fluids. The movement of the fluid (endolymph) in the semicircular canal sends signal to the brain for the change in the position. The vestibule has saccule and utricle. It gathers the information, which is related to a change in the plane.
