Figure 316 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. The differences in size and shape of cilia and microvilli are well illustrated by scanning micrographs of the lumenal surface of the epithelium lining the mammalian oviduct. The tufts of cilia associated with individual ciliated cells project several microns above the convex apices of nonciliated cells covered with short microvilli. The number of ciliated cells in this epithelium is under hormonal control by estrogens. A copy of the chapter is available on the ASCB's BioEDUCATE website.
