Giant Ear Model with Three Parts for anatomy studies is five times life size, non-breakable and depicts the organ of hearing and balance. Contains 36 features, hand numbered on the model.
Five times life size, this non-breakable reproduction depicts the human organ of hearing and balance. To simplify tracing the path of soundwaves, the surrounding temporal bone of the skull has been sagittally sectioned along the entire length of the model. The overlying temporal bone has also been cut away exposing the entire middle ear chamber and the labyrinth. Two of the middle ear ossicles, the malleus (hammer) and incus (anvil), and the attached, see-through tympanic membrane lift out for hands-on study. The labyrinth unit; consisting of the cochlea, vestibule, semicircular canals, auditory nerve and the stapes (stirrup); is detachable. Two of the three semicircular canals are made of transparent plastic tubing filled with colored fluid representing the endolymph. A visible air bubble in each will shift position when tilted, demonstrating the function of the canals in maintaining equilibrium. 36 features, hand-numbered on the model, are identified in the accompanying key. Dimensions are 16" x 11" x 7".
