Tongue specimens were collected from 18 healthy adult Egyptian geese (Alopochen aegyptiacus) of both sexes. We measured and analyzed the whole, anterior, middle and posterior length and width of the tongue parts. The dorsal mucosal surface of each tongue was investigated by SEM. The length of whole tongue, widths at anterior and middle ends of its root showed significant differences between sex...

Ten adult common quail of both sexes were used in this study. The tongue of adult common quail is characterized by a triangular format. On the dorsal surface of the apex and body of the tongue a median groove is found. L...

Subjects were asked to assess the bitterness of one 6-n-propyl-2-thiouracil (PROP) and two quinine HCl (QHCl) concentrations presented via filter papers of varying sizes. The number of taste papillae stimulated by these filter papers was counted in each individual. Whole mouth sensitivity to PROP was determined in a separate session. In support of other demonstrations of spatial summation, thes...
