Fig. 10. Medial aspect of the membranous labyrinth

The commencing seperation into utricle and saccule is seen.

The cochlea (figs. 9 and 10) is beginning to show a constriction at its junction with the vestibule, but the ductus reuniens so formed is as yet very wide. The ductus cochlearis is short and thick, and of its windings only two-thirds‘ of a turn are completed. It lies very close to the middle ear recess and causes a bulging into its roof, as already mentioned.
