Fig. 342. The anterior end of an embryo of Callorhynchus antarcticus (Shark)

viewed from the ventral side. (Norma frontal is). (According to Schauinsland.)

The composition of the vertebrate head shape indicates a low-lying are identical in the main parts of the higher forms of development: the front part of the skull with frontal process, the nasal pits, the eye, through the pharyngeal membrane bay mouth closed, bounded on both sides by the mandibular arch (mandibular arch). Side come from the occipital the gill arch to unite in the middle. The second of which is commonly referred to as the hyoid arch. The gill filaments are dotted. The heart is in the range of the branchial arches as in the human embryo.

Fig. 342. Das vordere Körperende eines Embryo von Callorhynchus antarcticus (Haifisch)

von der ventralen Seite betrachtet. (Norma frontalis.)

(Nach Schauinsland.)

Die Zusammensetzung des Wirbeltierkopfes einer tiefstehenden Form zeigt sich in den Hauptteilen identisch mit dem der höheren Entwicklungsformen: der Stirnteil des Schädels mit Stirnfortsatz, die Nasengruben, das Auge, die durch eine Rachenmembran geschlossene Mundbucht, zu beiden Seiten begrenzt durch die Unterkieferbogen (Arcus mandibularis). Seitlich kommen vom Hinterkopf die Kiemenbogen um sich in der Mitte zu vereinigen. Der zweite davon wird gewöhnlich als Hyoidbogen bezeichnet. Die Kiemenfäden sind punktiert. Das Herz liegt im Bereich der Kiemenbogen wie bei dem menschlichen Embryo.
