The repetitive structure of the walls of the brain tube is here again and especially clearly noticeable: the base plate, base plate, the alar plate and the cover plate. At the boundary between primary and wing plate runs the sulcus limitans (Fig. 602 and 604). The top plate is a Ependymlamelle, emerges from the case of mammals and humans, the pineal Corpus. The sulcus limitans is identical to the sulcus limitans (Monro) the systematic anatomy, which is continued in the hypothalamic sulcus.

Die immer wiederkehrende Gliederung der Wandungen des Hirnrohres ist hier aufs Neue und besonders übersichtlich bemerkbar: die Bodenplatte, die Grundplatte, die Flügelplatte und die Deckplatte. An der Grenze zwischen Grund- und Flügelplatte verläuft der Sulcus limitans (Fig. 602 und 604). Die Deckplatte stellt eine Ependymlamelle dar, aus der bei den Säugetieren und dem Menschen das Corpus pineale hervorgeht. Der Sulcus limitans ist identisch mit dem Sulcus limitans (Monroi) der systematischen Anatomie, der sich in den Sulcus hypothalamicus fortsetzt.
