Abstract: | Summary The authors studied the structure of the aortic wall of chick embryos during embryonal development and after hatching up to the age of 1 month. The typical morphology appears on about the seventh day of incubation; it is established on the twelfth day and it does not change afterwards, there is only an increase in the relative quantities of its morphological components. The aorta is of muscular type in its caudal half, while its cranial half is elastic. The cultures of the elastic cranial half and of the muscular caudal half gave the same results already obtained from the explantation in vitro of elastic arteries (anonyma and pulmonary arteries) and of muscular arteries (carotid).
