Oviduct - Atrophy

    Narrative
    Oviduct - Atrophy in a female B6C3F1/N mouse from a chronic study. The fimbria in the infundibulum are small and collapsed (arrow) and the folds of epithelium in the isthmus are blunted (asterisk).

    Oviduct - Normal in a female B6C3F1/N mouse from a subchronic study. The fimbria in the infundibulum (arrow) and epithelial folds in the isthmus (asterisk) are well formed (compare to Figure 1).
