Abstract
The three-dimensional fibrillar arrangement of the basilar membrane in the mouse cochlea was studied using scanning electron microscopy. Fibrils of the basilar membrane were exposed by removing cellular elements of the cochlea using a sodium hydroxide maceration technique. The arrangement of fibrils in the basilar membrane was different between the pars arcuata and pars pectinata. In the pars arcuata, fibrils were arranged in radial and spiral direction, showing a woven pattern. In the pars pectinata, most of the fibrils ran in the radial direction. These findings suggest that the vibration pattern of the pars arcuata and pars pectinata is different when the basilar membrane vibrates.
