Abstract

AbstractCilia‐bearing cells have been observed near the bottom of the crypt of the human circumvallate papilla, between the lower taste buds and the duct of von Ebner's gland. It is likely that they serve one or more of the following functions: cleansing the papillary crypt, circulation of tastants, and bathing the pores of the taste bud in the various fluid secretions of the oral cavity.The kinetosomes of these cells were observed to possess typical transitional fibers and rootlets with periodic structure. In addition, a single, lateral, satellite‐like projection from the midregion of the kinetosome was connected to microtubules which coursed deeply with the mitochondria‐rich cytoplasm as did fine fibrils and some rootlets.
