Magnified 50 times

(After His.)

The unsymmetrical anlage (primordia) is obvious, the right pulmonary system is considerably longer than the left. The first traces of Breakdown shows the left lung sacs two, left three bud-like Distension. The existing pipe is made ​​of endodermal cells in the interior, including its branches dotted the surrounding mesoderm shows the known cells of this tissue.

Fig. 407. Lungenanlage eines menschlichen Embryo,

4,3 mm Nackensteißlänge. 50 mal vergr.

(Nach His.)

Die unsymmetrische Anlage ist sehr auflfallend, die rechte Lungenanlage ist erheblich länger als die linke und zugleich weiter. Als erste Spuren der Gliederung zeigt das linke Lungensäckchen zwei, das linke drei knospenartige Auftreibungen. Das aus Entodermzellen bestehende Rohr im Innern ist samt seinen Verzweigungen punktiert, das umgebende Mesoderm zeigt die bekannten Zellen dieses Gewebes.
