The handplate (anterior footplate) is no longer
circular but develops
angles which correspond to the future digits. The posterior footplate is
also distinguishable from the lower part of the leg. It is possible to
see the pigmentation of the pigmented layer of the retina through the
transparent cornea. The tongue and brain vesicles are clearly visible.
