Fig. 535. The aortic arch in the shark embryo (Pristiurus)

Where the original relations of the aortic arch to the gills still exist.

Seen from below.

(Partly to Dohrn.)

The forehead is removed by a frontal section. The heart is away, on the ventral wall of the foregut is the truncus arterioles and divided, with most selachians, in 6 aortic arch on each side, the Foregut enclose an arc to lead into dorsal to the aorta. Much of this behavior of the truncus arteriosus versa in mammals and humans again. (See Figures 537 and 538)

Fig. 535. Die Aortenbogen eines Haifischembryo (Pristiurus)

bei dem die ursprünglichen Beziehungen der Aortenbogen zu den Kiemenbogen

noch bestehen. Etwas von unten gesehen.

(Teilweise nach Do hm.)

Der Vorderkopf ist durch einen frontalen Schnitt abgetragen. Das Herz ist entfernt, auf der ventralen Wand des Kopfdarms liegt der Truncus arteriosus und teilt sich, bei den meisten Selachiern, in 6 Aortenbogen für jede Seite, die den Kopfdarm bogenförmig umgreifen, um in die Aorta dorsalis einzumünden. Ein großer Teil dieses Verhaltens des Truncus arteriosus kehrt bei den Säugetieren und dem Menschen wieder. (Siehe die Fig. 537 und 538.)
