Fig. 616. Brain of a young Shark (Callorliynclius antarcticus)

Approximately the same age as that depicted his head and his skull skeleton Figure 258, 259

Here, the broad outline are shown five of the brain in a lower vertebrate. To the elongated body occur following Einzelnheitenivon front enumerated backwards pointed out: the nasal capsule to the optic tract runs olfactorius, the elongated telencephalon (telencephalon), Mes-encephalon (midbrain), the metencephalon (hindbrain), myelencephalon (After-him). The diencephalon (Zwischenhim) is not visible when viewed from above because of the strong bending of the brain tube. Nerves of the trigeminal nerve are visible bar and that the III. Branch of the optic nerve and nerve trochlear. The original 12 times magnified at Schauinsland

Fig. 616. Gehirn eines jungen Callorliynclius antarcticus

ungefähr desselben Alters wie jener, dessen Kopf und dessen Schädelgerüst abgebildet

wurde. Fig. 258, 259.

Hier soll die weitreichende Fünfgliederung des Gehirns bei einem niederen Wirbeltier gezeigt werden. An dem langgestreckten Organ treten folgende Einzelnheitenivon vorn nach hinten aufgezählt, hervor : die Nasenkapsel zu der der Tractus olfactorius zieht, das längliche Telencephalon (Endhirn), Mes- encephalon (Mittelhirn), das Metencephalon (Hinterhirn), Myelencephalon (Nach- him). Das Diencephalon (Zwischenhim) ist bei der Betrachtung von oben wegen der starken Knickung des Hirnrohres nicht zu sehen. Von Nerven sind sicht- bar der Trigeminus und zwar dessen III. Ast, der Nervus opticus und der N. trochlearis. Das Original bei Schauinsland 12 mal vergr.
