Deluxe Eight-Part Ear
Our most detailed ear model
provides a more complete perspective of the middle and inner ear structures
within 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 and 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, demonstrates the sense of
balance. Transparent tubing with colored liquid represents two of the
semicircular canals. An air bubble in each will move when tipped, demonstrating
the canals’ function in equilibrium. The other half of the labyrinth, upon
removal, shows the vestibular and cochlear nerves, which join to form the
auditory nerve. The cochlea itself separates into halves to reveal cochlear,
vestibular and tympanic ducts and the branching of the cochlear nerve.
- 95 hand-numbered features are identified in the corresponding key.
- Overall dimensions: 17x11x8 inches (43x28x20 cm) overall.
