Definition

Vestibular End Organ

The vestibular end organ is located in the inner ear next to the cochlear of the auditory system. The end organ comprises two components. The three semicircular canals, which are roughly orthogonal, sense rotational head movement while the two otolith organs (utriculus and sacculus), which are also orthogonal, sense linear head acceleration.

Processing

Signals from the vestibular end organ carry head velocity and acceleration information that is modified at the level of the brainstem to control the eye movements that stabilize vision when the head moves (vestibuloocular reflex) and to control the muscles that control posture and balance (vestibulospinal reflexes).

Detailed Description

Sensory System

The vestibuloocular reflex (VOR) is mediated by the six semicircular canals and four otolith organs (horizontal, anterior and posterior canals, and the utricle and saccule from both inner ears). The canals are arranged in such a way that each canal on the...
