(After Retzius) enlarged

The olfactory lobe is separated from tight angles to the brain pulls him forward Suicus the olfactory, lateral to the anterior edge of the island, behind which the gyrus olfactorius lateralis extends to invade after a sharp bend in the nearest to the front portion of the temporal lobe (comp. Fig. 615). Easy is the gyrus ambiens, the gyrus semilunaris seen also the optic chiasm to the optic nerve, which infuse Bulum, the following saccularis eminence, the cerebral peduncles, and medulla oblongata with cerebellum bridge. On the basal surface of the temporal and occipital no furrows are well defined at this time.

Fig. 619. Hirnbasis eines menschlichen t Fetus vom Anfang des 6. Monats.

(Nach Retzius.) Vergrößert

Der Lobus olfactorius ist dicht an dem Hirn quer abgetrennt Von ihm nach vorn zieht der Suicus olfactorius, lateral der vordere Rand der Insel, hinter dem der Gyrus olfactorius lateralis hinzieht, um nach einer scharfen Biegung in den zunächst liegenden vorderen Abschnitt des Temporallappens einzudringen (vergl. Fig. 615). Leicht ist der Gyrus ambiens, der Gyrus semi- lunaris erkennbar, ferner das Chiasma mit dem Nervus opticus, dem Infundi- bulum, der folgenden Eminentia saccularis, die Pedunculi cerebri, Brücke und Medulla oblongata mit Cerebellum. Auf der basalen Fläche des Temporal- und Occipitallappens sind noch keine Furchen um diese Zeit deutlich ausgeprägt.
