Structural organization and orientation of hair cells of the macula of the saccule of the membranous labyrinth of Rana temporaria

: Morphological peculiarities of the hair cells in the saccular macula of the internal ear have been studied by means of scanning electron microscopy in the Rana temporaria. Two main types of the hair cells are described: central and marginal. Cineciliary poles of the hair cells are oriented in two mutually opposite directions, in consequence, the macula is divided into two orientation zones.
