Section at the level of the brain
Due to the strong bending of the head in this preparation the brain has been sectioned in two regions and a cross section of the tail region is visible as well.
1 = Myencephalon
2 = Anterior cardinal vein
3 = Mandibulary arch
4 = Diencephalon
5 = Neural fold
6 = Section of the uterine wall
7 = Tail region
8 = Head region
Section at the level of the heart region
Also here, the tail region has been sectioned due to the bending of the embryo.
