| Abstract: | The surface patterns of the oviduct of Gallus domesticus were examined by scanning electron microscopy (SEM) using several preparatory techniques. Ciliated epithelial cells predominate throughout the oviduct with nonciliated cells approaching an equal proportion in the magnum and isthmus. Short, randomly oriented mucosal folds which characterize the infundibulum increase in height and longitudinal orientation as they approach the magnum. Here and in the isthmus they broaden and become dimpled with glandular apertures. The folds narrow again in the uterus and vagina. Cryofracture followed by SEM demonstrate the deeper mucosal folds and submucosal tubular system. |
