Secretion granules in the ciliated cells of the avian oviduct.
The avian oviduct is subdivided into five regions according to its function in egg formation and histological features. They are the infundibulum, albumen secreting region (magnum), isthmus, shell gland (uterus), and vagina. The epithelium of these regions consists of ciliated and nonciliated cells. In addition to secretion granules, specific to each region, in the non-ciliated cells, considera...
متن کاملSperm transport in the cow: peri-ovulatory redistribution of viable cells within the oviduct.
Using a surgical approach involving double ligatures and transection, together with subsequent recovery of the eggs, heifers mated at the onset of oestrus have been examined for progression of spermatozoa within the oviducts relative to the time of ovulation; the latter occurred 28-31 hours after the onset of oestrus. Evidence was obtained that spermatozoa competent to penetrate the egg(s) do n...
متن کاملMotility of the oviduct and uterus of the cow during the oestrous cycle.
Recordings of electrical activity of the oviduct and uterus were obtained during three oestrous cycles in cows fitted with an extra-cellular multi-electrode assembly. The stages of the cycle were identified by the appearance of the cervico-vaginal secretions and changes in the peripheral plasma level of progesterone were determined by radioimmunoassay. A gradual transition from local non-propag...
متن کاملThe Effects of Regular Fluid Secretion from the Uterus of Laying Hens on the Longevity and Fertilization Ability of Fowl Sperm in the Oviduct
The aim of this study was to examine whether the secreted fluid from the uterus influences the survival and fertilization capacity of fowl sperm in the hen oviduct. Hens with either regular uterine fluid secretion or irregular uterine fluid secretion were artificially inseminated through the transfer of sperm into the uterus. Twenty-four hours after artificial insemination, 3 hens with regular...
متن کاملSecretory Cells and Morphological Manifestation of Secretion in the Mouse Oviduct
The structure of secretory cells and granules has been described in the mouse Fallopian tube during sexual maturation and oestrous cycle. The oviducts of newborn mice were lined with a simple columnar epithelium in which only tall indifferent cells of uniform appearance were present. In some of these cells, marks of ciliogenesis were observed. The occurrence of secretory cells showing proteosyn...
