Electrical properties and gustatory responses of various taste disk cells of frog fungiform papillae.
We compared the electrical properties and gustatory response profiles of types Ia cell (mucus cell), Ib cell (wing cell), and II/III cell (receptor cell) in the taste disks of the frog fungiform papillae. The large depolarizing responses of all types of cell induced by 1 M NaCl were accompanied by a large decrease in the membrane resistance and had the same reversal potential of approximately +...
متن کاملLingual tactile acuity, taste perception, and the density and diameter of fungiform papillae in female subjects.
A growing body of evidence suggests that individuals who differ in taste perception differ in lingual tactile perception. To address this issue, spatial resolution acuity was estimated for 83 young adult females (52 Asians and 31 Caucasians) by their ability to examine with the tongue and identify embossed letters of the alphabet. Ratings of the magnitude of the bitterness of 0.0032M 6-n-propyl...
متن کاملDenver Papillae Protocol for Objective Analysis of Fungiform Papillae
The goal of the Denver Papillae Protocol is to use a dichotomous key to define and prioritize the characteristics of fungiform papillae (FP) to ensure consistent scoring between scorers. This protocol builds off of a need that has arisen from the last two decades of taste research using FP as a proxy for taste pore density. FP density has historically been analyzed using Miller & Reedy's 1990 c...
متن کاملChanges in fungiform papillae density during development in humans.
The anterior region of the human tongue ceases to grow by 8-10 years of age and the posterior region at 15-16 years. This study was conducted with 30 adults and 85 children (7-12 year olds) to determine whether the cessation of growth in the anterior tongue coincides with the stabilization of the number and distribution of fungiform papillae (FP) on this region of the tongue. This is important ...
متن کاملLingual nerve injury after third molar removal: Unilateral atrophy of fungiform papillae
BACKGROUND Pain and sensory changes due to lingual nerve injury are one of the most common alterations that follow surgical removal of third molar. They are usually transient but other less common complications, such as the atrophy of fungiform papillae, have an uncertain prognosis. CASE DESCRIPTION We report a case of a 34-year-old woman who presented a unilateral lingual atrophy of fungifor...
