Arch Otolaryngol. 1962;75(4):312-328. doi:10.1001/archotol.1962.00740040321004

The submicroscopic structure of the sensory cells of the membranous labyrinth has been the object of numerous recent studies with the aid of the electron microscope. We must remember the work of Engström and Wersäll1,2; Engström, Sjöstrand and Wersäll3; Engström and Sjöstrand4; Smith5-7; Smith and Dempsey8; Spoendlin9,10; Engström11,12; Friedmann13,14; Iurato and Bertoletti15; Iurato16-19 on the sensory cells of Corti's organ and that of Wersäll, Engström and

Hjorth20; Smith6,21; Wersäll22-24; Engström and Wersäll2; Friedmann13,14; Bairati, Jr., and Iurato25; Pietrantoni and Iurato26; Bairati,27 and Engström28 on the vestibular sensory cells.

The results obtained have clarified numerous points left in doubt by previous research done with the light microscope and have revealed new and important data, particularly with regard to our understanding of the functioning mechanism of these receptors.

The present treatise takes into
