A Study on the Biophysical Characteristics of the cat Labyrinth

Abstract

An investigation was made of the biophysical dimensions of the cat labyrinth. In each semicircular canal the diameter of both membranous and osseous canals and their radii of curvature were measured. From these measurements the length of the canal and its volume were calculated. The volume of sacculus, utriculus, endolymph and perilymph were also calculated after measuring their areas in histological serial sections. Distances between canals were also measured and the angles between them were determined. The data were used for calculating the constants of the fundamental differential equation of the cupula-endo-lymph system.
