In the sagittal section.

(After His.)

The foregut pulls strongly curved over the back of the tongue-caudal downward and divides into the esophagus and the underlying dorsal ventral Aditus larynx and trachea. Lying between front and rear tongue of Thyroglossal duct to the already deep in the underlying media shield glandular system. Dorsally extends into the cranial base and to Cranial cavity, the system of the hypophysis.

Fig. 355. Kopfdarm, Zunge, Mandibuiarbogen (= Unterkiefer) und primitive Nasenhöhle von einem menschlichen Embryo von 9,1 mm. Im Sagittalschnitt.

(Nach His.)

Der Kopfdarm zieht stark gekrümmt über den Rücken der Zunge kaudal- wärts und teilt sich in den dorsal liegenden Ösophagus und den ventral liegenden Aditus laryngis und die Trachea. Zwischen Vorder- und Hinterzunge zieht der Ductus thyreoglossus zu der bereits in der Tiefe liegenden medialen Schild- drüsenanlage. Dorsal erstreckt sich in die Schädelbasis hinein und bis zur Schädelhöhle die Anlage der Hypophysis.
