Misschien heb je hier iets aan:

The dorsal surface of the tongue is covered by numerous whitish elevations, the filiform papillae. Interspersed among them are isolated reddish prominences, the fungiform papillae, occurring mostly on the anterior part of the tongue. The circumvallate papillae, which are considerably larger, lie posteriorly. They do not project from the tongue but are surrounded by a trench. The foliate papillae appear as a series of parallel slitlike folds on the lateral borders of the tongue, near the anterior pillars of the fauces. They vary in length and can easily be confused with lesions. Lingual tonsils may be considered components of Waldeyer's ring and are seen posteriorly at the back of the tongue.

The lingual nerves (branches of the 5th cranial nerves) supply general sensory innervation, and the chorda tympani fibers (of the 7th cranial nerves) innervate the taste buds of the anterior 2/3 of the tongue. Behind the circumvallate papillae, the glossopharyngeal nerves (9th cranial nerves) provide the sensations of touch and taste. Nerve integrity can be determined by testing taste on both sides of the dorsum of the tongue with sugar, salt, vinegar, and quinine. Sweet and salty taste receptors are located at and near the tip; sour, on the sides; and bitter, on the most posterior part of the tongue. The hypoglossal nerves (12th cranial nerves) control movement of the tongue.
