Taste threshold, anatomical form of fungiform papillae and aging in humans.
The purpose of this study was to investigate the changes in taste sensitivity during aging using four standard taste solutions. The subjects consisted of 50 normal volunteers who were divided into two groups. The younger age group was composed of 27 individuals between the ages of 20 and 30 years. The older group consisted of 23 individuals between the ages of 50 and 77 years. In order to evalu...
متن کاملHuman taste: response and taste bud number in fungiform papillae.
The number of basic taste qualities registered by single human fungiform papillae is correlated with the number of taste buds borne on these papillae. Multiple sensitivity was demonstrated both in single fungiform papillae and in single taste buds, with response to all four of the basic taste qualities occuring in a single taste bud.
متن کاملTaste fiber responses during reinnervation of fungiform papillae.
Crushing or transecting the chorda tympani nerve of the gerbil (Meriones unguiculatus) caused ipsilateral degeneration of taste buds in the fungiform papillae. In less than two weeks some taste fibers regenerated into the tongue and formed new taste buds and receptor cells. The recovery process was evaluated electrophysiologically in 53 gerbils by acute recording proximal to the nerve injury si...
متن کاملGap junctions among taste bud cells in mouse fungiform papillae.
Introduction Mouse taste buds in fungiform papillae consist of ∼50 cells (TBCs; unpublished data), but only a few of them have synaptic contacts with taste nerves (Kinnamon et al., 1993; Seta and Toyoshima, 1995). Neither chemical nor electrical synapses/gap junctions have been confirmed in mammalian taste buds, though a subpopulation of TBCs expressed a variety of neurotransmitter receptors (K...
متن کاملTechnique to collect fungiform (taste) papillae from human tongue.
The sense of taste is critical for human life. It informs the body about the quality of food that will be potentially ingested and stimulates metabolic processes that prepare the alimentary canal for digestion. Steady progress is being made towards understanding the early biochemical and molecular events underlying taste transduction (for a review, Breslin and Spector, 2008). However, progress ...
