The labyrinth, or inner ear, evolved very early in vertebrate history and, with many variations in configuration but none of basic design and function, has been retained by all vertebrates.[well established][VHOG]
inner ear has parts membranous and osseuous/bony labyrinth. it's not clear where the EMAPA term 'labyrinth' belong, we place them here for now
