Abstract study of embryology provides a logical basis for the topog-raphical anatomy, explanation of many congenital anomalies and a scaffolding for further studies in obstetrics and gynacology (Wendell Smith and Williams, 1984). Morphology of the ovary, as other organs, can not be thoroughly understood without a good knowledge on its development (Mossman and Duke, 1973). The question of how a testis or an ovary develops from its early embryonic primordium, is given a rather simple answer in most elementary textbooks. For more than a century, many very good biologists have discussed the question and debated theoretical interpretations without reaching a general agreement (Jost, vigier, prepin and Perchellet, 1973). In clarifying these 1 , : < problems of uncertainty, the development of mammalian foetal ovary was investigated at various levels (light and electron microscopy) with particular reference to each ovarian structure (Odor, 1960; Odor, and Blandau, 1969; Mossman and Duke, 1973; Pelliniemi, 1975 & 1976; Byskov, 1978, Baker and Scrimgeour, 1980; Noden and de Lahunta, 1985; Latshaw, 1987). In regards to the ovary of the buffalo foetus, some studies were carried out on its morphology and structural changes (Gha- nnam and Deeb, 1967 & 1969; El-Ghannam and El-Naggar, 1974 & 1975, Abuzaid, Cartee and El Nahla, 1989). |
