The wall of the fallopian tube includes an elaborately folded mucosa surrounded by a muscularis. In the ampulla, shown here, the mucosa is quite elaborate and the muscularis is relatively thin.
The simple columnar epithelium of the mucosa contains both secretory cells and ciliated cells. Mucosal folds occupy most of the potential lumenal space, so that cilia on the epithelial surface can effectively move the egg toward the uterus.
