Fig.4. Drawing of a model constructed from sections of a 19 mm Embryo

The orbital wings are seen ascending almost vertically from the median mass (C.S.). A nucleus of chondrification is seen at O.W. This is connected by a bridge of connective tissue and procartilage with the corpus sphenoidale (C.S.).
