Gustatory Papillae

The morphology of the lingual papillae on the tongue of the fawn round-leaf bat (Hipposideros cervinus) was studied by scanning electron microscopy to determine its functional role in feeding ecology. Both mechanical and gustatory papillae were detected on the lingual surface. Large pronged papillae at the lingual apex provide a rake-like surface that facilitates quick retrieval of insect prey that may be trapped by the wing and tail membranes. These papillae also provide additional traction and act as a barrier, preventing the insects from escaping. Additional securing and gripping structures include the crowned filiform papillae situated on the anterior half of the tongue. Conical papillae on the lateral and medial aspects of the lingual root serve as a protective barrier to the lingual mucosa, and aid in directing insect fragments towards the oesophagus. The pair of small vallate papillae at the lingual root may reflect a compromise in gustatory potential. Taste perception may be a secondary feature in food selection of this bat and fungiform papillae may resume a more important mechanical function. Collectively, the lingual papillae of H. cervinus portray an adaptation to mechanical manipulation of food, instead of taste perception, which may not be of primary importance to insect feeders.

Although the anatomy of the gastrointestinal tract has been characterized in the lowland tapir (Tapirus terrestris), the exact anatomy of its tongue has not been studied. Samples of the lingual papillae and lingual glands were collected from the tongue of an adult female lowland tapir. The microscopic analysis of the structure of the lingual papillae and the histochemical analysis of the secretion of the lingual glands were analyzed. The tongue of the tapir is divided into the apex, body with a distinct lingual prominence, and the root. Its ventral surface is smooth. The most numerous of the mechanical papillae were the filiform papillae, while numerous conical papillae with a sharp apex or more rounded papillae were present in the root of the tongue. There were also nine vallate papillae and pair of foliate papillae. The foliate papillae contained several folds parted by 12–14 grooves. The mucous secretion produced by the lingual glands was more obvious than the serous secretion. The features of the dorsal surface of the tongue as well as the shape and number of the lingual papillae on the surface of the tongue of the examined female tapir differ compared to Equidae or Rhinocerotidae, the other two representatives of Perissodactyla. However, further study is necessary for the synapomorpy of the tapir’s tongue.

Abstract The purpose of this study was to describe the distribution and surface structure of the lingual papillary system in four male adult English horses by scanning electron microscopy. The animals were supplied from the Jockey Club of Turkey (TJK). Tissue samples were taken from the dorsal, ventral and lateral surface of the apex, corpus and radix of the tongue. Filiform papillae were distributed mainly on the dorsum, being abundant, very long and with a slim cylindrical form with pointed endings or multi-bifurcated terminations at the apex. These papillae were typically conical in shape with a wider base in the corpus of the lingua and absent on the radix of the lingua. Fungiform papillae were mainly on the lateral surfaces and lobulated forms were also observed. The horses have two large vallate papillae, located on the dorsum close to the caudal part of the tongue. These papillae were surrounded by a prominent gustatory groove. The vallate papillae had many taste pores opening into the papillary groove. The foliate papillae were observed just rostral to the palatoglossal arches. These papillae have many variable sized taste pores which open into the grooves between the papillary leaves. The papillary leaves were covered with concentrically arranged cornified cells of variable appearance. However, there were no lingual papillae on the ventral aspect of the horse’s tongue.

The present study was conducted on the tongue of six apparently healthy indigenous (Bos indicus) cows of different age and sex and they were collected from local market at Dinajpur district and this research work was conducted in the Department of Anatomy and Histology, Dinajpur Government Veterinary College, Dinajpur during the research period from the month of July 2003 to April 2004. After proper euthanasia, the animals were killed and then the tongues of these animals were dissected out from the carcasses and fixed in 10% neutral buffered formalin solution. In the present study it was observed that the tongue of indigenous cow (Bos indicus) of Bangladesh has three parts: the root, body and an apex. The dorsum linguae was specially more pronounced in its centre and was occupied by numerous types of masticatory and gustatory papillae. The fine rasp-like filiform papillae were more numerous and directed caudally throughout the dorsum and packed closely in front of the fossa linguae throughout the tip, whereas, the club shaped fungi form papillae were irregularly distributed all over the dorsum among the filiform papillae. The broad headed lentil shaped lenticular papillae was also found in the rostral two-thirds of the dorsum but better developed along the mid-line of the tongue. The large conical papillae of the tongue of Bos indicus occurred in the rostral two-thirds of the dorsum with a higher concentration in the middle portion of the tongue, however, the small ones occurred through out the torus. The vallate papillae of the tongue of Bos indicus were 12-20 in number on either side and dispersed in two irregular rows (25-40) in total along the caudolateral two-thirds of the dorsum. The mucosa of the root of the tongue of Bos indicus did not show any specific papillae but it was rather smooth due to diffused lymphoid tissue distribution (lingual tonsil).

The mammalian tongue has evolved for specialized functions in different species. The structure of its papillae tells about the animal's diet, habit, and taxonomy. The opossum has four kinds of lingual papillae (filiform, conical, fungiform, vallate). Scanning electron microscopy of the external features, connective tissue cores, and corrosion casts of the microvasculature show the filiform papillae have a spearhead-like main process and spiny accessory processes around the apical part of the main process. The shape and number of both processes depend on their position on the tongue. On the apex, the main processes have shovel-like capillary networks and the accessory processes have small conical networks. On the lingual radix, the processes have small capillary loops. In the patch region, conical papillae have capillaries arranged as a full sail curving posteriorly. The fungiform papillae are scattered among the filiform papillae and have capillary baskets beneath each taste bud. Giant fungiform papillae on the tongue tip are three to four times larger than the ones on the lingual body. Capillaries of giant papillae form a fan-shaped network. The opossum has three vallate papillae arranged in a triangle. Their tops have secondary capillary loops but not their lateral surfaces. Mucosal folds on the posterolateral border have irregular, fingerlike projections with cylindrical capillary networks. These findings and the structure of the rest of the masticatory apparatus suggest the lingual papillae of opossum have kept their ancestral carnivorous features but also developed the herbivore characteristics of other marsupials.

Abstract The morphology and histological structure of two adult Brandt’s hedgehog, Paraechinus hypomelas, (Brandt, 1836) tongue were examined by light and scanning electron microscopy. On the dorsal surface of the tongue, three types of papillae were observed: filiform, fungiform and vallate papillae. Apex and corpus of the tongue as well as the lateral surface of the corpus were covered with numerous filiform papillae with bifurcated tip, while the epithelium lining the ventral lingual surface was free from papillae. Discoid shape fungiform papillae were scattered over the entire surface of the lingual apex, corpus and lateral surface uniformly between the filiform ones without regional variation in number and size. Three elliptical or oval vallate papillae in an inverted triangle form were found on the root of the tongue. Each papilla had a lobulated and very irregular dorsal surface. Both fungiform and vallate papillae contain taste buds. The foliate papillae was absent. Overall, the present findings reveal that despite some similarities, the lingual papillae of the Brandt’s hedgehog as an omnivore animal has spices-specific characteristics compare to the Erinaceous auritus as an insectivore species. This finding provides a set of basic data about the morphology of tongue and its lingual papillae in Brandt’s hedgehog.

In the light of recent molecular studies, there are two phylogenetic species of the red panda (Ailurus fulgens): Ailurus fulgens fulgens and Ailurus fulgens styani. The red panda belongs to the endangered species living in the wild only in Asia and is included in the CITES list. Although the biology and diet of this species has been extensively described, the histological structure of the tongue and lingual glands has not yet been characterized in detail in relation to the lifestyle of this mammal under specific conditions and as a basis for comparative anatomical studies of the biodiversity of endemic species. Study samples were collected from two adult males of Ailurus fulgens f. held in Wrocław Zoological Garden. Both tongues were examined macroscopically; moreover, samples with lingual papillae for light microscopy and scanning electron microscopy (SEM) were collected from the apex, body and root of the tongue. Both tongues of the Ailurus fulgens f. males were approximately 9 cm long. The dorsal lingual surface was covered with mechanical and gustatory lingual papillae. Filiform papillae were observed on the apex and the body of the tongue, while small conical papillae were observed on the root of the tongue. An elongated, 1–1.5 cm long cylinder-shaped lyssa was observed in the ventral part of the apex. Moreover, most numerous and largest round in shape fungiform papillae were observed on the apex and on the border of the body and root of the tongue, located directly rostrally to 12–13 round and oval in shape vallate papillae. The SEM study showed that filiform papillae on the apex had several long secondary processes, while filiform papillae on the body of the tongue were taller and their secondary papillae were shorter than the equivalent structures on the apex of the tongue. The SEM study showed numerous taste pores on the surface of the fungiform papilla, while irregular surface of the vallate papillae, however some of them had smoother surface. Mixed glands (comprised of mucous acini and serous acini) were present within the vallum (within the connective tissue core) of the vallate papilla. Beneath the papillae more serous glands were observed, while the posterior lingual glands in the caudal part of the root of the tongue were mucoserous (mucous units were prevalent). A characteristic feature of the tongue of Ailurus fulgens f. was the presence of lyssa, which is comparable to other representatives of Carnivora, but the number of vallate papillae was individually variable. The lack of strongly developed mechanical conical papillae probably may be related to the type of plant food that is particularly dominant in red panda. Further differences between Ailurus fulgens f. and Ailurus fulgens s. cannot be excluded. The results of these studies may be useful especially for veterinarians specializing in working with exotic animals and people dealing with wildlife conservation.

Bradypus Variegatus

The Bradypusvariegatus inhabits the forests of South America and feeds from leaves, branches and sprouts from different plants. Due to its diet and the lack of literature on the morphological aspect of Xenarthras, five Bradypusvariegatus tongues from animals which died from natural causes were evaluated, and they came from Pará State Museum Emílio Goeldi and were donated to the Laboratory of Animal Morphological Research (LaPMA) from UFRA, for revealing the different types of papillae and epithelial-connective tissue. Macroscopically, the tongues presented elongated shape, rounded apex, body, root, median sulcus in the root's apex, and two vallate papillae. The mucous membrane of the tongue revealed a keratinized stratified pavement epithelium, while the ventral surface of the tongue was thin and smooth, not provided with any type of papillae. However, the dorsal surface of the tongue was irregular with the presence of three types of papillae: filiform, fungiform and vallate papillae. The filiform papillae found were of a simple type, presenting a rounded base, irregularly distributed with a larger concentration and development on the tongue's apex and body. The fungiform papilla showed a practically smooth surface with irregular format, with the presence of gustatory pores; these were found all over the dorsal surface, with larger concentration at the rostral part of the apex. Only two vallate papillae were observed disposed in the root of the tongue, surrounded by a deep groove, and revealing several taste buds. The tongues from Bradypusvariegatus presented gustatory papillae similar to the ones described for other Xenarthras species and wild mammals.

The instintive behaviour exhibited by insects in the selecting  food is always a matter of  interests to entomologists, and it is one of the fundamental principles underlining the application of entomology to agriculture, horticulture and forestry. Food seclection is an important characteristic of insects that help them survive in periods with insufficient foods.Three grain types of food, maize grain, long-grain rice and soybean grain, were used in this sudy for detecting food selection behaviours of maize weevil, Sitophilus zeamais. Grains were kept in box traps put in the different stores in Son La during 90 days. The result showed that maize weevil, Sitophilus zeamais, prefered traps with maize grains (71.4%) considerably more than ones with long-grain rice (14.3%) and soybean grain (14.3%). Meanwhile, the cornsap beetle, Carpophilus dimidiatus, was mostly observed in maize grain (98.5%) and to a lesser degree, in soybean grain (1.5%); and the dried-fruit beetle, Carpophilus hemipterus, was abundantly observed in maize grain (93.1%) and less in soybean grain (6.9%). The red flour, Tribolium castaneum, also tended to select all the three food grain, i.e. maize grain: 53.5%, long-rice grain: 35.2%, and soybean grain: 11.3%.Comparing f beetle individuals captured on three types of food grains showed that the maize weevil, Sitophilus zeamais, is the most abundant species. The percentage this store beetle among all beetles observed in maize, soybean grains and long-rice grains were 57.0%, 84.9% and 27.6%, respectively. Interestingly, Ahasverus advena, foreign grain beetle, occurred abundantly on long-rice gain (61.7%), i.e. this grain is a suitable food for the development of this beetle.
