ectoderm, future tectum, mesencephalon, mesoderm, neural plate, optic area, optic groove, prosencephalon (forebrain), trigeminal neural crest (CN V)

A section through the open curved part of the prosencephalon showing its junction with the mesencephalon.

Observe:
1. The optic area that will form the optic vesicle, which will eventually become the retina of the eye.
2. The continuity of the ectoderm with the neural plate.
3. The trigeminal neural crest that blends with mesodermal cells in the area.
