The histology and ultrastructure of the oviduct of three ostriches are described. The ostriches were obtained at the stage just before oviposition. The oviduct wall consists of a mucous membrane carrying mucosal folds showing side branching. The pseudostratified columnar or tall simple columnar epithelium covering the lumen contains ciliated and non-ciliated cells. The ultrastructure of the two cell types and the glandular cells of the lamina propria is described. The vagina has no glands in the subepithelial connective tissue. Beyond the connective tissue, the oviduct wall has two layers of smooth musculature. The inner layer consists of circularly disposed fibres some of which continue into the subepithelial connective tissue to ultimately enter the core of the mucosal folds. The outer layer contains oblique and longitudinally arranged fibres and is peripherally bound by a serous covering. |
