Intra epithelial capillaries of immature and mature oviduct of indigenous geese (Anseranser)‎ : histometrical study

الملخص EN

A total of twelve oviducts of indigenous geese were used in this study.

In immature geese the four parts of oviduct were lined by simple cuboidal to low simple columnar epithelium.The mean height of cuboidal epithelium was 20±1μm, and 29±2μm for columnar epithelium and at this period the intra epithelial capillaries were not observe in all parts of oviduct.

The mature and laying geese the epithelium lining has changed into ciliated pseudostratified columnar epithelium which its height has measured about58±3μm in isthmus and 60±1μm in magnum.

The intraepithelial capillaries were appeared only in the isthmus and magnum regions and most of these capillaries in the isthmus have arranged between the basal cells at the basement membrane.

The intra epithelial capillaries of magnum region were observed at the center of epithelium
