Scanning electron micrograph of the surface of the epithelium of a human oviduct, at mid-cycle. The tufts of cilia (in red) associated with individual ciliated cells project several microns above the convex apices of non-ciliated cells covered with short microvilli (in sepia). Estrogen regulates the number of ciliated cells in this epithelium.
