Abstract : The squirrel monkey (saimiri sciuria) is probably one of the most useful experimental primates in recent days. They are small, not very difficult to handle, inexpensive primates, and good for all kinds of vestibular and cochlear functional experiments, behavioral conditioning, and so on. Since all inner ear sensory end organs are only purely mechanically stimulated in the vital bodies under natural circumstances, it is worthwhile to know the anatomical construction before performing any functional experimentation. For this purpose, the horizontal serial sections are excellant for acquiring good three-dimensional figures of the inner ear structures. All illustrations in this monograph will be limited within the usual anatomical (light-microscopical) structures, not extending to ultrastructures. Part I of this monograph includes a series of microphotographs of the horizontal serial sections under low magnification (about 20x). This series is the right ear viewing from superior. Part II includes higher magnification views of some important structures from this series and from the other animals, and some humans. Part III includes several bilateral temporal bone microphotographs (horizontal sections) of squirrel monkeys and cats. The modiolar angle and the posterior semicircular canal plane are clearly demonstrated in the series. (Author)
