The morphological characteristics of the oviduct of 12 sexually mature rheas (Rhea americana) were studied. Only the left oviduct is developed as a long tube with a length of 122 ± 23.1 cm, and is subdivided into infundibulum (15.2 ± 4.0 cm), magnum (63.3 ± 9.4 cm), isthmus (5.6 ± 3.1 cm), uterus (16.0 ± 4.2 cm) and vagina (11.5 ± 1.4 cm). The mucous membrane of the oviduct, as a whole, possesses luminal folds covered by ciliated columnar epithelium with secretory cells. The infundibulum part… Expand

Ultrastructure of the bullfrog (Lithobates catesbeianus‐Shaw, 1802) oviduct in different seasons
A comparison of the morphology of the oviducts collected during different seasonal periods suggests that the frogs have greater reproductive potential in the spring due to the development of the structures related to the Oviduct, presence of developed cilia, and electron‐dense granules. Expand
Light, Scanning and Transmission Electron Microscopical Study on the Oviduct of the Ostrich (Struthio camelus)
Nine mature female ostriches (Struthio camelus) aged 37- 49 months were used for the present study and it was revealed that the lining epithelium of the oviduct is folded and formed of pseudostratified columnar ciliated cells. Expand
A preliminary study on the glycosylation of the reproductive tract in the Ostrich (Struthio camelus camelus).
Glycosylation of the reproductive tract of an adult female Red-necked ostrich carrying a fully formed calcified egg in her uterus when accidently killed by a blow to the head, was examined using lectin histochemistry on samples from the infundibulum, magnum, uterus and vagina. Expand
Comparative Study Morphology on Genital Tract between Local Iraqi Hen and Duck.
The analyses indicated that the mean weigth, length as well as width of the five regions of the oviduct in mature hen were significantly differences greater than in duck, and noticed that increase from immature parameters to mature ages in hens and duck, but in heens parameters the increases was higher significant.

Comparative Histomorphology of the Ovary and the Oviduct in Rabbits and Pigeons
The differences observed in the structures of the ovaries and of the oviducts of rabbits and pigeons might be due to their different reproductive functions in parturition (viviparity and oviparity, respectively). Expand
The study includes (10) females indigenous adult turkey hens (Meleagris gallopavo), these birds purchased from local supplier in Diala city, Iraq. The age of these birds about (45-55) weeks and theExpand
Immunolocalization of Intermediate Filaments and Laminin in the Oviduct of the Immature and Mature Japanese Quail (Coturnix coturnix japonica)
The immunolocalization of desmin, SMA and laminin in the oviduct of the Japanese quail is similar to that in the domestic fowl, however, differences in the immunoexpression of vimentin inThe LE of the two avian species were shown to exist. Expand
Gross and Histomorphological Study of the Ovary and Oviduct of Turkey Hen with Especial Emphasis on the Sperm-Host Gland
Turkey bird is one of the popular poultry species which is reared primarily for meat production and considered as one of the major sources of animal protein. With such importance of this species,Expand


The fine structure of the infundibulum and magnum of the oviduct of Gallus domesticus.
The mucous membrane of the infundibulum and magnum of the hen's oviduct is modified for the receipt and fertilization of the yolk and the elaboration of the bulk of the solid material making up theExpand
Morphological Features of the Luminal Surface of the Magnum in the Sexually Immature Ostrich (Struthio camelus)
It is suggested that ovarian activity and changes in daylength have a profound effect on the surface features of the magnum in the immature ostrich. Expand
SEM preparation and observations of the hen's oviduct
The surface patterns of the oviduct of Gallus domesticus were examined by scanning electron microscopy (SEM) using several preparatory techniques to demonstrate the deeper mucosal folds and submucosal tubular system. Expand
Sperm-storage tubules in the vagina of the ostrich (Struthio camelus).
Sperm-storage tubules were located in a 200-mm-wide band of the vagina adjacent to the utero-vaginal junction and contained a basal nucleus and displayed extensive apical junctional complexes. Expand

The avian oviduct functions as a biological assembly line, beginning sequentially with the deposition of the albumen around the fertilized or unfertilized ovum, then the shell membrane, and lastly, the shell, within 25 hr of ovulation. Expand
The fine structure of the secretory cells of the uterus (shell gland) of the chicken
The secretory processes in the shell gland of laying chickens were the subject of this study and it was postulated that the microvilli of both cells are active in the production of the cuticle of the shell. Expand
Evidence of sperm storage in the female ostrich.
Sperm storage occurs in ostrich hens and fertile eggs can be laid for at least 5 to 8 days after copulation, and further studies are required to demonstrate the maximum period during which stored sperm are capable of successful fertilization. Expand
