Inertia can be portrayed as the propensity of matter, for example, the endolymph liquid in the vestibular mechanical assembly to stay very still if very still, or, if moving, to continue moving in a similar heading. At the point when a man starts to turn, the latency of the endolymph causes the cupula to twist the other way. As the turn proceeds, be that as it may, the latency of the endolymph is overcome and the cupula fixes. Right now, the endolymph and cupula are moving in a similar bearing and at a similar speed. On the off chance that the development is all of a sudden ceased, the more prominent dormancy of the endolymph makes it keep moving in the first heading of turn and to twist the cupula toward that path – bringing on incitement of the basic hair cells.
