FUNCTIONAL EAR MODEL

Functional Ear Model


Functional Ear Model
This model shows how the tympanic membrane, ossicles, the complex internal ear with cochlea and the oscillations of the Basilar hearing membrane operate and interact. The mirror enables operation of the model for the studying of various ear functions from different angles at the same time. One single model may be studied by several students simultaneously in an action-oriented learning situation.











Budget Ear Model
This twice life-size anatomical model of the human ear features a removable bone section to reveal the auditory ossicles with eardrum and labyrinth showing cochlea, auditory nerves and semicircular canals











Desktop Ear Model
1.5 times life-size anatomical model provides accurate representation of the outer, middle and inner ear. Mounted on base.










Life-Size Ear Model
One piece, life-size anatomical model of the human ear shows outer ear, ear canal, and inner ear mechanisms, including ossicles, cochlea, nerve and eustachian tube. Mounted on plastic base










Life-Size Auditory Ossicles
Life-size replicas of the three tiny bones of the middles ear - the malleus (hammer), incus (anvil) and stapes (stirrup) - cast from actual human specimens. Ossicles are labeled and embedded in plastic for protection.












Giant Budget Ear
Intended for elementary school science classes, this anatomical model shows all the major structures relating to hearing and balance. Dissects into 3 parts. 4 times life-size.









4-Part Human Ear
Three times life-size, this anatomical model of the human ear provides a faithful and highly detailed representation of the outer, middle and inner ear. Removable eardrum with hammer, anvil and stirrup, as well as 2-part labyrinth with cochlea and auditory / balance nerve.









6-Part Human Ear
Same as above, but with two additional removable bone sections to close the middle and inner ear










Giant Three-Part Human Ear
This anatomical model of the human ear is 5 times life-size. Made of an unbreakable polymer, this ear 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 the 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 functions 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. 26 hand-numbered features.










Giant Student Ear
The same main mold was used to create this anatomical model of ear as the one listed above. However this ear does not have the transparent tubes used for demonstrating equilibrium, but is dissectible. The hammer, anvil, transparent ear drum and the labyrinth all lift out for detailed hands-on study. Functions of the 18 hand-numbered primary features are explained in detail in the accompanying student guide

Deluxe Eight-Part Ear

5 times life-size in unbreakable vinyl, our most detailed ear model provides a more complete perspective of the middle and inner ear structure with the temporal bone. All the skin has been peeled off the detachable auricle to expose its cartilaginous structure, muscles, auricular arteries and nerves, as well as the entrance to the auditory canal. Sections of the petrous and mastoid portions of the temporal bone can be lifted off to expose the middle an inner ear chambers. The tympanic ring with its see-through tympanic membrane and attached ossicles can also be lifted out. The extractable labyrinth is dissectible into three portions. Half of it, consisting of the semicircular canals and vestibule, demonstrate the sense of balance. Transparent tubing with colored liquid represents two of the semicircular canals. An air bubble in each will move with tipped, demonstrating the canals' function in equilibrium. The other half of the labyrinth, upon removal, shows the vestibular and cochlear nerves, which joint to form the auditory nerve. The cochlea itself separates into halves to reveal cochlear, vestibular and tympanic ducts and the branching of the cochlea nerve
