Fig. 638. Semilunar ganglion human embryo of 6.9 mm length (4 weeks old)

(Qasseri).

Horizontal section through the head of a human embryo of 6.9 mm length (4 weeks old).

Reconstruction. (According to Dixon.)

On the average, the brain appears in the tube brocken bow, with the beginning of the myelencephalon is made. The semilunar ganglion (Gasserian) comes with its sensory and motor root in the mesoderm of the Head out. The outgoing from the ganglion nerve is the nerve alveolar inferiorly. The reconstruction, however, the course of the nerves in the lower jaw not taken. Ciliary ganglion, the sphenopalatine ganglion and the otic are not yet detectable. Between the maxillary and mandibular protrusion the primitive oral cavity visible.

Fig. 638. Ganglion semilunare (Qasseri).

Horizontalschnitt durch den Kopf eines menschlichen Embryo von 6,9 mm Länge

(4 Wochen alt).

Rekonstruktion. (Nach Dixon.)


Auf dem Schnitt erscheint das Hirnrohr im Bereich der BrOckenbeuge, wobei der Anfang des Myelencephalon getroffen ist. Das Ganglion semilunare (Gasseri) mit seiner sensibeln und motorischen Wurzel tritt im Mesoderm des Kopfes hervor. Der aus dem Ganglion abgehende Nerv ist der N. alveolaris inferior. Die Rekonstruktion hat aber den Verlauf des Nerven im Unterkiefer nicht getroffen. Ganglion ciliare, Ganglion sphenopalatinum und oticum sind noch nicht nachweisbar. Zwischen Oberkieferfortsatz und Mandibularbogen ist die primitive Mundhöhle sichtbar.
