The vestibular system, in vertebrates, is a sensory system that creates the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea , a part of the auditory system , it constitutes the labyrinth of the inner ear in most mammals .
The leans is a type of vestibular illusion in flight which causes spatial disorientation. The process involves the semicircular canals of the vestibular system. The semicircular canals detect angular acceleration. In total, there are three semicircular canals: the anterior, posterior, and lateral canals.
Diagram of inner ear and vestibular system Animation demonstrating how the hairs in the semicircular canal detect angular motion, the input lag, and eventual acclimation to angular motion The vestibular system , which is responsible for the sense of balance in humans, consists of the otolith organs and the semicircular canals .
The primary role of the vestibular system is to maintain head and eye coordination, upright posture and balance, and conscious realization of spatial orientation and motion. The vestibular system is able to respond correctly by recording sensory information from hairs cells in the labyrinth of the inner ear.

This test can provide site-specific information on vestibular system and its function. [ 25 ] Another way of testing the VOR response is a caloric reflex test , which is an attempt to induce nystagmus (compensatory eye movement in the absence of head motion) by pouring cold or warm water into the ear.
Equilibrioception is the result of a number of sensory systems working together; the eyes (visual system), the inner ears (vestibular system), and the body's sense of where it is in space (proprioception) ideally need to be intact. [1]
The inner ear contains the vestibular system, which is also known as the organ of equilibrium.About the size of a pencil eraser, the vestibular system contains two distinct structures: the semicircular canals, which detect changes in angular acceleration, and the otolith organs (the utricle and the saccule), which detect changes in linear acceleration and gravity.
