Figure 5

Inter-specific comparison of the orientation patterns of ciliary bundles on the macula sacculi. Ciliary bundles of all three species (A-C) are arranged into two horizontal groups on the ostium, two vertical groups on the cauda, and again two horizontal groups in the posteriormost region of the cauda of the macula. Note that the arrows point into the direction of the kinocilia indicating the orientation of the ciliary bundles in the respective area while the dashed lines separate different orientation groups. Scale bars, 100 μm.
