“…The origin of the testicular artery from the cranial renal artery in the ostrich is similar to that reported in the domestic fowl (Nishida, 1964;Kurihara and Yasuda, 1975) and pigeon (Bhaduri et al, 1957). This was considered to be the general pattern of arterial supply to the testes in the ostrich and occurred in 54.2% of the specimens examined (see Fig.…”

“…1). The incidence of this particular pattern in the fowl is reported to be 54.5% (18 out of 33 specimens examined, Kurihara and Yasuda, 1975) and represents the type IV variation described by both Nishida (1964) and Kurihara and Yasuda (1975). The remarkable similarity in the incidence of this pattern in both the fowl and ostrich would seem to lend support to the suggestion that this is the general pattern observed in birds.…”

SummaryThe macroscopic features of the arterial supply to the reproductive system of the male ostrich was studied in 16 pre-pubertal and eight sexually mature and active birds. The left and right cranial renal arteries arise from the aorta, between the cranial divisions of the kidneys. These vessels supply the cranial divisions of the kidneys, the testes, the epididymides and the cranial segments of the ducti deferentia. Accessory testicular arteries which arise directly from the aorta are present in 45.8% of the specimens. They supply the testes and cranial parts of the ducti deferentia. They are variable in number and origin, and four variants are identified. A cranial ureterodeferential branch originates from the cranial renal artery, supplies the cranial portion of the ductus deferens and ureter, and runs caudally to anastomose with the middle renal artery. The sciatic artery arises laterally from the aorta, just caudal to the acetabulum, and gives rise, ventrally, to a common trunk, the common renal artery, which divides into the middle and caudal renal arteries. The middle renal artery gives rise to the middle ureterodeferential branch which supplies the middle part of the ductus deferens and ureter. A few centimetres caudal to openUP (August 2007) the kidney, the aorta terminates in three branches, namely, the left and right internal iliac arteries and the median caudal artery. The internal iliac artery divides into the lateral caudal artery and the pudendal artery; the latter gives off caudal ureterodeferential branches that supply the caudal segments of the ductus deferens and ureter. In addition, the pudendal artery gives off vessels that supply the cloaca, some of which continue to the base of the phallus, where they form an arterial network. In conclusion, the pattern of the blood supply to the reproductive organs of the male ostrich is, in general, similar to that of the domestic fowl and pigeon, although there are a few highlighted distinctive features.

The lack of genital ridge vascularization in the early chick embryo: Implications in the migration of the primordial germ cells

et al. 1998

View full text Add to dashboard Cite

It is known that chick primordial germ cells (PGCs) in early embryonic development migrate via the blood vascular system to colonize the gonadal anlagen. Classically, two factors have been involved in the extravasation of PGCs from the blood stream: chemotactic and mechanical factors. An accurate knowledge of the vascular system of the genital ridge is therefore necessary. However, development of gonadal vascularization in bird embryos has been scarcely studied. Our previous studies have shown that the gonadal arteries develop from the mesonephric arteries. The purpose of this work was to study the implications of the development of the vascular system of the chick genital ridge on PGCs colonization. We selected the Hamburger and Hamilton (H-H) stage 18, since the genital ridge is well developed and PGCs actively extravasate. Forty chick embryos of this stage were processed for scanning electron microscopy of vascular corrosion casts and of critical point-dried specimens as well as light microscopy. Our results are conclusive. We could not find any vessel or capillary network supplying the genital ridge; the dorsal aorta and the primordia of the mesonephric arteries were the closest vessels. However, numerous interendothelial spaces were found in the dorsal aorta at the level of the genital ridge. It is suggested that the interendothelial gaps may be very important in the exchange of substances between the avascular genital ridge and the aortic endothelium at this developmental stage. Two different routes are thought to be involved in PGC migration to the gonadal anlage at this stage: the aortic endothelium and the mesonephric arteries. Whereas mechanical factors may be important for extravasation of PGCs in the mesonephric arteries, no reasons have been found from the morphological point of view to support a slowness of the blood flow in the dorsal aorta at the level of the genital ridge facilitating the extravasation.
