Figure 3.

Static elastic deformation of the lch5 organ. (A) Increase of total length with lateral deflection, entire organ (black squares), cap cells (red circles), and neuronal part (blue triangles). (B) Relative increase in length versus relative lateral deflection amplitude for four different lch5 organs, each from a different larva. (C) Shapes of a representative lch5 organ (same as Fig. 2) traced from a video recording while the organ was increasingly deflected. (D) Shapes of another representative lch5 organ traced from a video recording while the organ was increasingly deflected (black squares and red cubic spline interpolation line) and during relaxation (red circles and blue cubic spline interpolation line). See also Movies S2 and S3. In (C), part of the last curve has been shown as a dotted line, because this part of the organ was obscured by the needle in the frame of the video corresponding to this curve. The last points in (A) and (B) are encircled in green for the same reason, and represent a lower bound for the value of the length of the organ at that point. To see this figure in color, go online.
