from the main stems of the nerve ganglion hervorgelienden

in a human embryo of 15.5 mm Scheitelsteißlänge (barely seven Weeks old), seen from inside. The brain is shown in full screen for

better orientation. (According to Dixon.)


Upper and lower jaw and mouth opening after sagittal sections are connected in a way the bulbus oculi, but is again in full for better orientation Rounding drawn. Moreover, the whole face of preferred and enlarged to make room for the individual parts. There are visible:

First the ophthalmic nerve, ciliary ganglion to the top of the bulb.

Second The maxillary nerve to the ganglion. nerve and the sphenopalatine pterygoid canal (Vidii) to the geniculate ganglion of the N. facialis, which still not enclosed by the cartilaginous ear capsule.

Third The mandibular nerve with the ganglion. otic and its connection with the N. vagus (Gangl. nodosum).

4th The motor root of the trigeminal ganglion along the draws.

5th N. glossopharyngeal and vagus uppermost in their course. (About other branches, which develops in human embryos of this age already are, see Dixon.)

Fig. 639. Das Qanslion semilunare (Qasseri) uod die Hauptstämme der aus

dem Ganglion hervorgelienden Nerven

bei einem menschlichen Embryo von 15,5 mm Scheitelsteißlänge (kaum sieben Wochen alt), von innen gesehen. Das Gehirn ist im Vollbild eingezeichnet zur

besseren Orientierung. (Nach Dixon.)


Ober- und Unterkiefer und Mundspalte sind nach Sagittalschnitten kon- struiert, der Bulbus oculi ist aber wieder zur besseren Orientierung in voller Rundung eingezeichnet. Überdies ist der ganze Gesichtsteil vorgezogen und vergrößert, um Raum für die einzelnen Teile zu gewinnen. Es sind sichtbar gemacht :

1. der Nervus ophthalmicus mit dem Ganglion ciliare oberhalb des Bulbus.

2. Der Nervus maxillaris mit dem Gangl. sphenopalatinum und dem Nervus canalis pterygoidei (Vidii) zum Ganglion geniculi des N. facialis, der noch nicht von der knorpeligen Ohrkapsel umschlossen ist.

3. Der Nervus mandibularis mit dem Gangl. oticum und dessen Verbindung mit dem N. vagus (Gangl. nodosum).

4. Die motorische Wurzel des Trigeminus zieht dem Ganglion entlang.

5. N. glossopharyngeus und Vagus in ihrem obersten Verlauf. (Über andere Äste, die bei menschlichen Embryonen dieses Alters schon entwickelt sind, siehe Dixon.)
