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
