title: [Thr arteries of the male sex organs of Japanese quail (Coturnix coturnix japonica) and their development after hatching].
abstract: A total of 83 male Japanese quails of the following age groups were used for this study: 11, 18, 25, 32, 35, 37, 39, 41, 43 days, and 7, 9, 17 weeks after hatching. Neoprene-Latex, Tensol-Cement, and the china ink were injected via the aortic arch. In most of male Japanese quails, the testes are supplied by the A. testicularis originated from the Aorta descendens through a common trunk with the A. renalis cranialis. But in only 3 quails had this artery originated directly from the Aorta descendens on either side. In 9 quails had the A. testicularis accessoria originating independently from the Aorta descendens and running cranially or caudally in short distance to the normal A. testicularis. The arteries for the Ductus deferens were divided into 3 categories. The Rami ureterodeferentiales craniales were spread out from A. testicularis or Rami epididymales. The Rami ureterodeferentiales medii came from the A. renalis media and the A. renalis caudalis. The Rami ureterodeferentiales caudales originated from the A. caudae lateralis and A. pudenda. The Receptaculum ductus deferentis, the Corpus vasculare paracloacalis and the Phallus nonprotrudens in the Cloaca were supplied from the thick Ramus cloacalis of the A. pudenda. The Ramus bursalis of this artery supplied the Glandula proctodaealis and the Bursa cloacalis, and was also thick. The arteries to the genital organs were observed in the 11 day old male quail. The A. pudenda began developing at about 30 days after hatching when the quail's body matured. While the A. testicularis began developing at about 40 days after hatching when the male Japanese quail was full of the spermatogenic activity.
