Fig. 4 lateral view of a model reconstructed from a human fetus 50 mm CR length

The figures 4 to 9 represent a series of median and lateral views of wax-plate reconstructions of the membranous labyrinth and the surrounding perioticular tissue spaces, illustrating under the same scale of enlargement three typical stages in the development of these spaces. This figure shows a lateral view of a model reconstructed from a human fetus 50 mm. CR length (Carnegie Collection, No. 84). The scala vestibuli is in the first stage of its development and consists of a row of large reticular spaces which extend from the ventral margin of the cistern downward along the apical surface of the cochlear duct. The scala tympani is more advanced and shows more complete coalescence of its constituent spaces. Enlarged 9 diameters.
