====Fig. 27====
Median view of the same model shown in figure 26. This view shows the topography of the scala tympani. Its large proximal end lies opposite the fenestra cochleae (rotunda) and corresponds to the focus at which its development originates. Distally it tapers off rapidly where the spaces are smaller and their coalescence less complete. Enlarged 11.4 diameters.
