Hearing Lab 1
Models and Review (Noncadaver Lab)
To the Instructor: Because the structures in the hearing mechanism are so small, models are
really the best way to work on them. I have also included a list of figures that might be useful, all
of which are available in the Image Library section of the Instructor Resources CD-ROM.
Figure
9-1 Outer, middle, and inner ear
9-2 Pinna landmarks
9-3 Tympanic membrane landmarks
9-4 Articulated ossicles
9-5 Ossicles
9-6 Right middle ear cavity landmarks
9-7 Membranous labyrinth
9-8 Landmarks of the scala media
9-9 Landmarks of the organ of Corti
