Fig. 540. Aortic arch of a human embryo of 5 mm greatest length

including the pharynx and the inner gill-pouches.

(75 times enlarged.)

(According to Tandler.)

There are four pharyngeal pouches formed. Towering over the first beyond the pharynx. The conus arteriosus is still simple. There are five Aortic arch to see: the I, II, III, IV and VI. The sixth bypasses inner fourth pharyngeal pouch caudally and medially. He dismisses a small Branch to the tracheal system. At the mouth of the 6th aortic arch is an islet formation. The rising of the ventral pharyngeal part of the conus arteriosus, from which spring from the I. and II arch means Ventral aorta, the longitudinal strain, occur in the aortic arch is, Dorsal aorta. The third aortic arch is also called carotid arteries, the known as pulmonary sixth arch.

Fig. 540. Aortenbogen eines menschlichen Embryo von 5 mm gröfiter Länge

samt dem Pharynx und den inneren Kiementaschen.

(75 mal vergrößert.) (Nach Tandler.)

Es sind 4 innere Schlundtaschen ausgebildet. Die erste ragt hoch über den Pharynx hinaus. Der Conus arteriosus ist noch einfach. Es sind fünf Aortenbogen zu sehen: der L, IL, III., IV. und VI. Der sechste umgeht die vierte innere Schlundtasche kaudal-und medialwärts. Er entläßt einen kleinen Ast zur Trachealanlage. An der Mündungsstelle des 6. Aortenbogens findet sich eine kleine Inselbildung. Der an der ventralen Pharynxwand aufsteigende Teil des Conus arteriosus, aus dem der I. und IL Bogen entspringen, heißt Aorta ventralis; der Längsstamm, in den die Aortenbogen eintreten, heißt Aorta dorsalis. Der dritte Aortenbogen wird auch als Carotidenbogen , der sechste als Pulmonalisbogen bezeichnet.
