vestibular organ
consists of a bony labyrinth containing a membranous labyrinth in the inner ear. Part of the membranous labyrinth is the nonacoustic labyrinth or vestibular organ. The vestibular organ consists of the membranous saccule and utricle and semicircular canals. The semicircular canals contain balance end organs called cristae and the saccule and utricle contain similar end organs called maculae. The organ is essential in the maintenance of the animal's balance.
