Text-fig. 5. Sagittal section 19 mm embryo

On left, showing the intermediate stage in the changing aspect of the wall "of the cavity.

On the right, schemes to represent the method in which the change is brought about. A, B, F, alar, basal, and floor laminae.

The hinder limb of the U-groove is lost in the upper part of the true interlaminar sulcus. When the alar lamina begins to grow in thickness the interlaminar sulcus is pushed forward, so that it runs into the U-groove nearer its lowest part. This is seen in text-fig. 5, in which a sagittal section of the region in an embryo of 19 mm. is shown.
