Giant Three-Part Ear

Five-times life-size, this unbreakable polymer reproduction depicts the human organ of hearing and balance.

Sagitally sectioned along the length of the auditory canal and Eustachian tube, it is easy to trace the path of sound waves entering the ear, and it becomes clear how pressure is equalized on both sides of the eardrum. 

The entire middle ear chamber and the labyrinth is exposed to view. 

The malleus (hammer) and incus (anvil), and the attached see-through tympanic membrane lift out, as well as the entire labyrinth unit, for hands-on study. 

Two of the three semicircular canals are made of transparent tubing filled with colored fluid representing the endolymph.
