The membranous labyrinth which is enclosed by the bony labyrinth forms small sacs saccule and utricle and tubules semicircular ducts and cochlear duct. The structures of the internal ear are located within the petrous part of the temporal bone and is composed of two parts the bony and the membranous labyrinth. All three parts of the ear are important for detecting sound by working together to move sound from the outer part through the middle and into the inner part of the ear.
