前庭Kinociliumの微細構築

抄録

Fine structure of the guinea pig utricular kinocilium was examined with transmission electron microscopy in the use of tannic acid staining. Inner dynein arms and central pair of microtubules were selectively lacking, meanwhile outer dynein arms were typically observed. These findings seem to support the concept that the vestibular kinocilium is nonmotile or weakly motile.
