Fig. 614. Human fetus of 4 Month (10 cm CRL)

Seen from behind. The same brain as in Fig. 613.

(Anatomical Collection in Basel.)

The lateral hemisphere areas are still vöUig smooth. A recovery back to the medial surface as well Thalamusmulde caused by adaptation of the hemisphere wall at the convexity of the thalamus. The occipital lobes diverge, making the midbrain (mesencephalon) namely the quadrigeminal plate in large part is visible. The view from behind the cerebellum lies before the observer. His hemispheres stand out clearly as the dorsal surface of the diamond mine lying in front of the gracile funiculi. The cerebrum shows nowhere transient furrows. The fetus was immediately after the expulsion with formol 10: 100 injects, opened after a few days away, the skull and the brain.

Fig. 614. Qehirn eines menschlichen Fetus vom 4. Monat (10 cm Scheitel-


Von hinten gesehen. Dasselbe Gehirn wie in Fig. 613.

(Anatomische Sammlung in Basel.)

Die lateralen Hemisphärenflächen sind noch vöUig glatt. Eine Einziehung hinten an der medialen Fläche ist als Thalamusmulde wohl durch Anpassung der Hemisphärenwand an die Konvexität des Thalamus entstanden. Die Lobi occipitales weichen auseinander, wodurch das Mittelhirn (Mesencephalon) und zwar dessen Vierhügelplatte zu einem großen Teile sichtbar ist.

Bei der Ansicht von hinten liegt das Kleinhirn vor dem Beschauer. Seine Hemisphären treten deutlich hervor, ebenso die dorsale Fläche der Rauten- grube vor den Funiculi graciles liegend.

Das Großhirn zeigt nirgends transitorische Furchen. Der Fetus wurde direkt nach der Ausstoßung mit Formol 10 : 100 injiziert, nach ein paar Tagen der Schädel geöffnet und das Gehirn entfernt.
