Fig. 532. Development of the heart chambers and septa

Last stage. View the dorsal half. Schematically. (According to Hochstetter. From the manual of the history of O. Hartwig.)

The papillary muscles and trabeculae are carneae omitted. the Interventricular septum atriorum is now the heart of vaginal septum wall (atrio-ventricular septum), united with the medial endocardial cushion the former Canalis auricularis convey the connection. You and the septum atriorum are dotted. The medial endocardial cushion also supply some of material for the production of the atrioventricular valves. In the septum atrium, at its root, a single larger upper opening-up occurs, the foramen ovale. The septum is superior later its sickle-shaped closure.

Fig. 532. Ausgestaltung des Herzinnern. Entwicklung der Scheidewände.

Letzte Stufe. Ansicht der dorsalen Hälfte. Schematisch. (Nach Hochstetter. Aus dem Handbuch der Entwicklungsgeschichte von O. Hartwig.)

Die Papillär muskeln und die Trabeculae carneae sind weggelassen. Das Septum atriorum ist jetzt mit dem Septum interventriculare zur Herzscheiden- wand (Septum atrio-ventriculare) vereinigt, wobei die medialen Endokardkissen des früheren Canalis auricularis die Verbindung vermitteln. Sie und das Septum atriorum sind punktiert. Die medialen Endokardkissen liefern auch zum Teil Material für die Herstellung der Atrioventrikularklappen. In dem Septum atriorum ist an seiner oberen Wurzel eine einheitliche größere Öffnung aufge- treten, das Foramen ovale. Das Septum superius bildet später dessen sichel- förmigen Abschluß.
