The dimensions of the membranous labyrinth partly determine the mechanical operation of the semicircular canal system. This study provides, for the first time, extensive measures in individual specimens of the sizes, cross-sectional shapes and areas of the horizontal semicircular duct, ampulla and utricle in the rat and the guinea pig. The membranous labyrinths were fixed in Karnovsky's fixative, exposed, photographed, sectioned, oriented perpendicular to the line of sight and then measured using a calibrated graticule in the eye piece of an operating microscope. As well as the expected size differences between these species, there are major differences in the shape of the utricle.
膜迷路的尺寸部分决定了半规管系统的机械运作。本研究首次提供了大鼠和豚鼠水平半规管、壶腹和椭圆囊的大小、横截面形状及面积在个体标本中的广泛测量数据。膜迷路用卡诺夫斯基固定液固定，暴露后拍照，切片，沿垂直于视线的方向定向，然后在手术显微镜目镜中使用校准的分划板进行测量。除了这些物种之间预期的大小差异外，椭圆囊的形状也存在重大差异。
