Schematically. (After His Younger)

The heart of the vagus nerve are thin, thick, those of the sympathetic out- coated. By the vagus nerve and sympathetic ganglia of the next Branches form three plexuses: the trunk between the aorta and Bulbusgefl6cht Pulmonary artery, the network connection in the concavity of the aortic arch and plexus in the atrium of the upper wall of the sinus venosus and the right Forecourt. These braids form with nerve cells, which in the course of the Branches find themselves, the heart of the nervous system. Later penetrate the ends of the Nerve branches, which contain ganglion cells, with their processes in the Cardiac muscle one.

Fig. 651. Herzgeflecht menschlicher Embryonen zwischen 10 und 19 mm

Nackensteifllänge.

Schematisch. (Nach His d. J.)

Die Herznerven des Vagus sind dünn, jene des Sympathicus dick ausge- zogen. Die vom Nervus vagus und von den sympathischen Ganglien kommenden Äste bilden drei Geflechte: das Bulbusgefl6cht zwischen Truncus aortae und Pulmonalis, das Verbindungsgeflecht in der Konkavität des Aortenbogens und das Vorhofgeflecht in der oberen Wand des Sinus venosus und im rechten Vorhof. Diese Geflechte bilden mit den Nervenzellen, welche im Verlauf der Äste sich vorfinden, das Herznervensystem. Später dringen die Enden der Nervenzweige, welche Ganglienzellen enthalten, mit ihren Fortsätzen in den Herzmuskel ein.
