In man and the warm-blooded animals,tJieir use is apparently to impel secreted fluids or other matters along theciliated surface, as, for example, the mucus of the windpipe and nasalsinuses, which they carry towards the outlet of these cavities. Structure.—The cells of the ciliated epithelium (fig. 52) containoval nuclei, exhibiting for the most part a distinct intra-nuclear network. Fig. 53. Fiff.
