Description
We examined the bullfrog's saccule using light and scanning electron microscopy. We found no evidence of a striola. Type A hair cells were not only distributed peripherally, but also throughout the central macula, though far less frequently than the dominant type D. We distinguished two primary hair cell types, which corresponded to the ciliary patterns: type A cilia are associated with short, conical hair cells, and type D cilia are associated with long, cylindrical hair cells. Each displays at least one subtype, which may represent developmental precursors. The otolithic membrane is crisscrossed with tunnels and topped with statoconia.
