Fig. 647. Nervous System of a human embryo of 6.9 mm CRL

Seen from the left side. Magnification relative to the original about 20 times.

(After His.)


The embryo shows four pharyngeal arches. On the spokes of a wheel-together writhing bodies are seen as the main reference points for the head- the eye, the middle cranial beams and the maze bubbles L;: tonic

Xll means the hypoglossal nerve;

Vh. = Atrium of the heart;

Vt. = Ventricle of the heart;

Lb = liver. The metamerism of the peripheral nervous system is obvious in the first Line on the fuselage, but also the segmentation of the cranial nerves is well marked. The peripheral nerves are everywhere where there is no cut surfaces are specified, if drawn, as they were detectable. The Wurzelplexus plexus cervical sup. et are inferior in the making. The Sow in several places there.

Fig. 647. Nerveosystem eines menschlichen Embryo von 6,9 mm Nacken-

steifilänge,

von der linken Seite gesehen. Vergrößerung auf das Original bezogen etwa 20 mal.

(Nach His.)


Der Embryo zeigt vier Kiemenbogen. An dem radförmig zusammenge- krümmten Körper sind erkennbar als Hauptorientierungspunkte für die Kopf- nerven: das Auge, der mittlere Schädelbalken und das Labyrinthbläschen L;

Xll bedeutet den Nervus hypoglossus;

Vh. = Vorhof des Herzens ;

Vt. = Ventrikel des Herzens ;

Lb. = Leber. Die Metamerie des peripheren Nervensystems ist unverkennbar in erster Linie am Rumpf, aber auch die Metamerie der Kopfnerven tritt deutlich hervor. Die peripheren Nerven sind überall da, wo keine Schnittflächen angegeben sind, soweit gezeichnet, als sie nachweisbar waren. Die Wurzelplexus des Plexus cervicalis sup. et inferior sind im Entstehen. Die Ansäe an mehreren Stellen vorhanden.
