Fig.8. Coronal section of a 19 mm Embryo
Coronal section further forward than fig.7, showing (O.W.1) the posterior limb of the orbital wing which bounds posteriorly the optic foramen. The anterior limb is not yet chondrified. Between O.W. and O.W.1 the outgoing optic stalk is evident; H.S. is the hypophysis stalk; above it is a curious middle piece to the corpus sphenoidale, which, though appearing to be independent, is not so, as models prove. A.T.is the ala temporalis (greater wing); I.5, the 2nd branch of the Trigeminus; E.R.the external rectus. The chief interest in the figure is the independence of the orbital wing (O.W.1).
