Two types of sensory hair cell in the saccule of a teleost fish.
Previous investigations have demonstrated significant ultrastructural differences in hair cells located in various regions of the utricle of the oscar, Astronotus ocellatus. In this study, we used TEM and SEM to examine cells from the central and marginal regions of the saccule to determine if similar hair cell ultrastructural differences exist in this endorgan. Based upon ultrastructural characteristics, central saccular cells closely resemble utricular striolar cells while marginal cells are intermediate in ultrastructure between striolar and extrastriolar cells of the utricle.
