Fig. 6. From model of left middle ear region in 50 mm specimen

Somewhat simplified. Lower figure shows superficial view of recess seen from above and behind. Note position of 2nd pouch and its relation to the concavity, visible on the roof, which lodges the auditory capsule. The upper figure shows the cochlear portion of capsule cut away from the rest and turned round to exhibit the fossula rotunda. which lies over the pouch. Above this the facial nerve and stapes are seen cut, their other parts remaining on the other portion of the model. The thickness of the walls, of course, makes the pouch appear more prominent than it would be if the region were exposed as in the previous figures.
