Some Histological And HistochemicalStudies On The Ostrich Oviduct At Different Ages

Twenty five immature and mature ostrich females (struthio camelus) are used for carrying out the present work, to study the anatomy, histological and histochemical characteristics of the immature and the mature pre-Iaying and laying ostrich oviducts.The left oviduct is predominated at the left side while the right one is rudimentary at the right side of the coelom. The oviduct is formed from five main segments; infundibulum, magnum, isthmus, uterus and vagina. The present study demonstrated a great vThe mucosa of immature oviduct is thrown into many low thick longitudinally oriented folds, which increase in height and carry few small secondary ones towards the uterus and vagina. The lining epithelium of the oviduct of immature ostriches consists of cThe connective tissue of the propria is more fibrocellular. It contains glandular buds lined with cuboidal· cells . These buds firstly appear in the magnum, infundibulum and uterus.
