At 5 times life size, the surrounding temporal bone of the skull has been sagittally sectioned along the entire length of the auditory canal and Eustachian tube.

This simplifies tracing the path of sound waves entering the ear and makes it quite evident how pressure is equalized on both sides of the eardrum. T

he overlying petrous portion of the temporal bone has also been cut away exposing the entire middle ear chamber and the labyrinth. The malleus, incus and the attached seethrough tympanic membrane are removable, as is the entire labyrinth consisting of cochlea, vestibule, semicircular canals, auditory nerve and stapes.

Two of the three semicircular canals are made of transparent plastic tubes filled with coloured fluid representing the endolymph. A visible air bubble in each tube will shift position when tilted, demonstrating the function of the canals in maintaining equilibrium.

A spiral cutaway of the cochlea shows its three canals in contrasting colours to enhance teaching the concept of pitch.
