Histological study of oviduct in adult Iraqi Black Goat

The present study was aimed at the light microscopic examination of oviduct and show epithelium structure iraqi goat oviduct, determination histochemical mucus secreted by epithelial cells, muscular layers oviducts Twelve healthy adult constituted material study. using routine histological techniques Hematoxylin eosin , masson trichrom for Histochemically, it observed Pas Alcian Histological observations revealed that consists 4 mucosa, submucosa, tunica muscularis serosa. primary secondary folds increase both in number height infundibulum ampulla while less isthmus. Epithelium composed simple columnar, although seems pseudostratified some areas, contains ciliated secretory cells. Histomorphometric examinations three regions demonstrated mean thickness isthmus mucosa-submucosa More visibility cells mucosal thick transports sperm up; require promoting products were increased tip fold than base. Conclusion By lined pseudo-stratified columnar epithelium. Mucosal maximum tubual part infundibulum, least all stages animal. propria–submucosa comprised loose connective tissue with blood vessels, abundant amount collagen fibres few reticular fibers staining means PAS reaction, secretion progressively towards
