![]() The average numbers of taste buds per papilla are summarized in Table 1. Atrophic changes were observed in papillae of some men > 40 years old and some women > 55–60 years old, though Jurisch (1922) reported that the number of vallate papillae did not appear to change systematically as a function of age. Ninety-eight percent of all tongues have a central median papilla ( Fig. 2C). The number of vallate papillae per human tongue varies between 4 and 18 (n = 2264 tongues), with an average of 9.2 ± 1.8 papillae ( Münch, 1896). The papillae are innervated by an enormously large nerve fiber plexus originating from CN IX (see below) compared to the innervation of foliate or fungiform papillae. ![]() Taste buds are lined up in the mucosa of the trench walls around the bases of each vallate papilla ( Figs. 4C and F). They are round and measure between 2 and 8 mm in diameter. Vallate papillae lie directly anterior to the sulcus terminalis and extend in a V-shaped line across the root of the tongue ( Fig. 2).
