[Scanning electron microscope study of the ontogeny of human lingual taste buds].
The surface of the tongue in the newborn and elderly subjects was examined by scanning microscopy to demonstrate some types of taste papilla. The lingual chemosensory auxiliary apparatus was shown to undergo heterochronic maturation in different periods of ontogenesis. The taste buds first matured in the papilla localized on the body and root and then on the apex of the tongue. The changes occurring in the chemosensory apparatus have been demonstrated for two age periods (for 60- and 80- year-old subjects).
