The structure of the cochlea in some myomorph and caviomorph rodents

Authors


Abstract

The structure of the cochlea has been studied in 26 species of feral rodents from the Sub-Orders Myomorpha and Caviomorpha. The specimens were all intravitally perfused to obtain good preservation of the internal ear. The following measurements were made on the cochleae: the height and width of the cochlea, the number of half-turns, the width and thickness of the basilar membrane, the height of the cells of Claudius and the size of the spiral ligament; other special features were also noted.
