Fixation effects on the relation between the tectorial membrane and the cilia of the hair cells.

Abstract

The observation of unusual specimens induces one to suggest that, in vivo, the cilia of the hair cells are deeply immersed in the tectorial membrane. The cilia show their terminal parts free only when, due to fixation effects, they are drawn out from the tectorial membrane. This relationship induces one to reconsider the modality of excitement of the cochlear receptors.
