It consists of the bony framework for the cochlea as well as the three semicircular canals. The bony labyrinth houses the three semicircular canals and the two otolithic organs (the utricle and saccule). The vestibular system monitors the motion and position of the head in space by detecting angular and linear acceleration. The 3 semicircular canals in the inner ear detect angular acceleration and are positioned at near right angles to each other. Each canal is filled with endolymph and has a swelling at the base termed the ampulla. The labyrinth is a system of tunnels in the skull that contains the sensors for the auditory and vestibular systems.
