COMPARATIVE HISTOLOGICAL STUDY OF THE REINFORCED AREA OF THE SACCULAR MEMBRANE IN MAMMALS.
Abstract
The reinforced area of the saccular membrane is probably a structure protecting the macular end organ. An attempt has been made to investigate and compare this structure microscopically in 65 mammalian inner ears, including those of man. A definite reinforced area of the saccular membrane existed in all of the human ears examined. Its existence was also demonstrated in all of the squirrel monkey ears studied; however, some of these showed narrow or questionable formations. The ears of all the four-legged mammals investigated, on the other hand, showed no reinforced area except those of the flying squirrel. It is possible that, as a stimulus receptor, the function of the saccule in primates differs from that of the saccule in lower mammals. (Author)
