The neural tube is at the head and body still wide open and will end lamina as cerebral, cranial plate and lamina medullaris, called medullary But you can see the symmetrical halves already collected and Term to approach more and more.

von 2,11 mm Länge,

Alter etwa 13 — 14 Tage. Norma dorsalis. Rekonstruktion.

(Nach Eternod)

Das MeduUarrohr ist am Kopf und Körperende noch weit offen und wird als Lamina cerebralis, Hirnplatte und Lamina medullaris, MeduUarplatte be- zeichnet Man sieht jedoch die symmetrischen Hälften schon erhoben und im Begriff, sich mehr und mehr zu nähern. Im mittleren Abschnitt des Körpers ist die Platte zum MeduUarrohr geschlossen. Am Körperende setzt sich die MeduUarplatte zu beiden Seiten des CanaUs neurent6ricus weiter fort. Hinter dem Canalis neurentericus ist noch die Primitivrinne vorhanden. Es sind noch keine Kiemenbogen entwickelt, auch bei dem Embryo Fig. 585 nicht
