Three-Part Ear Model
 
 

DETAILS

5 times life-size, this unbreakable polymer reproduction depicts the human organ of hearing and balance. Sagittally sectioned along the length of the auditory canal and Eustachian tube, it is easy to trace the path of soundwaves 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. An air bubble in each 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 colors to teach the concept of pitch. 36 hand-numbered features are identified in the accompaning key.
