		In that period primordia of fungiform papillae are well-marked on the surface of the dorsum of the apex and body of the tongue.
		Fungiform papillae belong to the group of gustatory papillae, which are found on the tongue in the rabbit along with foliate and vallate papillae [1, 5].
		The arrangement of primordia of fungiform papillae on the dorsum of the apex and of the body of the tongue is similar to the distribution of epithelial thickenings, the presence of which was shown for day 18 and 20 of prenatal life.

		Fungiform papillae are distributed across the anterior (front) two-thirds of the tongue and are concentrated mostly near the tip.
		Fungiform papillae contain about 3 to 5 taste buds, and appear as red spots on the surface of the tongue.
		Foliate papillae are located in the lateral border (sides) of the tongue, and the taste buds are located along the folds on the sides of the papillae.

		The present report examined the morphology of fungiform papillae in adult rats that received bilateral chorda tympani transection at 10 days of age.
		Counts were made of fungiform papillae with a pore, fungiform papillae with no pore and fungiform papillae with a keratinized conical surface; a feature referred to as "filiform-like." Neonatal chorda tympani nerve transection resulted not only in a loss of taste buds but also in a permanent loss in numbers of fungiform papillae.
		Compared with an average of 152 fungiform papillae in sham-operated control rats, there was an average of only 54 fungiform papillae after neonatal chorda tympani transection.

		Fungiform papillae are concentrated on the anterior tip of the tongue and anterior lateral margins in humans and it has been demonstrated that NaCl threshold was inversely related to the number of fungiform papillae (more papillae = more sensitivity, lower threshold).
		In rats the bitter receptors are expressed in a subset of taste cells in all papillae but they are more concentrated in foliate and circumvallate papillae situated at the sides and the back of the tongue.
		Thermal stimulation of the anterior sides of the tongue in humans (fungiform papillae and the chorda tympani nerve) evokes sweet and salt/sour taste.

		The papilla is well-innervated, gustatory fibres innervate the taste bud (arrow) and perigemmal somatosensory nerve fibres innervate the surrounding epithelium.
		The NT3-dependent somatosensory innervation apparatus of the papilla appears intact, while the taste bud innervation (arrow) is almost non-existent.

		The filiform papilla is one of 4 types of lingual papillae, and its function is purely mechanical; it has no sensory structures associated with it, as do the others.
		They include: the fungiform papillae, which are less common than the filiforms; the vallate (or circumvallate) the largest and most prominent; and the foliate papillae, which are most easily seen in the Order Lagomorpha (rabbits, hares, and conies).
		This type of papilla is set into a deep pocket in the tongue's surface, and anchored at the bottom by a short broad stalk.

		(The most numerous papillae on the tongue--the filiform, or threadlike, ones--lack taste buds, however, and are involved in tactile sensation.) Of those with taste buds, the fungiform ("mushroomlike") papillae on the front part of the tongue are most noticeable; these contain one or more taste buds.
		The fungiform papillae appear as pinkish spots distributed around the edge of the tongue and are readily visible after taking a drink of milk or placing a drop of food coloring on the tip of the tongue.
		At the back of the tongue are roughly 12 larger taste bud—containing papillae called the circumvallate ("wall-like") papillae, which are distributed in the shape of an inverted V. Taste buds are also located in the foliate ("leaflike") papillae, small trenches on the sides of the rear of the tongue.
