The Giant Functional Ear Model is enlarged to 5 times life-size with functional equilibrium demonstration using visible air bubbles that move when tilted.

An anatomical ear model enlarged to 5 times life-size for easy teaching of the anatomy of the ear, including a functional equilibrium demonstration using visible air bubbles that move when tilted. The Giant Functional Ear Model offers the following features:

• 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 are 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 coloured 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 colours to teach the concept of pitch.

The Ear Model comes with an instructor's key with 36 hand-labeled parts.
