Fig. 698. The embryonic bulbus two human embryos at different stages of development of the eye cup

Both eyeballs from the 4th Weeks represented on average. The internal organization shows the following details: i vesicle optica secundaria äufeeren a double wall (lateral) and an inner (medial) lamella. Second A Linsengrübchen at the still open, according Koelliker. The rear wall of LinsengrObchens is also noticeable. Third The envelope by mesoderm. When B (van Bambecke) are the edges of the lens pit already grown and there is a lens vesicle is formed, which still related to the remaining ectoderm.

Fig. 698. Der embryonale Bulbus zweier menschlichen Embryonen auf verschiedenen Entwicklungsstufen des Augenbechers.

Beide Bulbi aus der 4. Woche, im Durchschnitt dargestellt. Die innere Organisation zeigt folgende Einzelheiten: i. Die Vesicula optica secundaria mit doppelter Wandung einer äufeeren (lateralen) und einer inneren (medialen) Lamelle. 2. Bei A das noch offene Linsengrübchen, nach Koelliker. Die hintere Wand des LinsengrObchens ist ebenfalls bemerkbar. 3. Die Umhüllung durch Mesoderm. Bei B (nach van Bambecke) sind die Ränder des Linsen- grübchens bereits verwachsen und es ist ein Linsenbläschen entstanden, das aber noch mit dem übrigen Ektoderm zusammenhängt.
