title: Dimensions of the horizontal semicircular duct, ampulla and utricle in the human.
abstract: This study provides measurements in individual specimens of the sizes, cross-sectional shapes and areas all around the path of fluid flow through the human horizontal semicircular duct, ampulla and utricle. These data were obtained from multiple measurements on individual specimens which had been fixed by immersion in Karnovsky's fixative and microdissected. The results are compared with similar measurements in the rat and guinea pig.
