Giant 3-part Ear W/chart & Key, 5x (NON-RETURNABLE)

Demonstrates equilibrium with liquid-filled canals

• Five 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’s 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 3 canals in contrasting colors to teach the concept of pitch
• Thirty-six hand-numbered features are identified in the accompanying key
• One of the Autographed Anatomy™ model series, this model is not only 100% American-made, but is also personally autographed and dated by its handcrafter!
• A FREE notebook version (8½ x 11”) of the full-color Heart Anatomy Chart is included; additional notebook charts and a poster version (22” x 28”) are also available (sold separately)
• Overall dimension: 16” x 11 x 7” (41cm x 28cm x 18cm)
• Warranty: Lifetime against manufacturer’s defects
