Abstract
A superstructure for the olfactory epithelium is described. The interrelationship of its cellular constituents and their relationship to the free surface of the epithelium is demonstrated. The microvilli in the olfactory region of man are shown to contain an array of filaments, whose pattern of distribution is demonstrated; their mode of branching is discussed. A distinct receptor zone consisting of the terminal processes of the peripheral olfactory neurones forming the outer third of the superstructure of the olfactory epithelium in the experimental mammals is demonstrated. Experimentally induced damage results in swelling and ultimate disintegration of these processes and invariably leads to the disappearance of the receptor zone. There occurs hypertrophy and increase in the number of microvilli of the supporting cells; physio-pathological deformities of their free surfaces are occasionally seen. Later events are recorded and at a week the appearance of the receptor end of the olfactory epithelium is shown.
